Disappointment for Norwich in the end after a valiant second-half effort. West Ham were worth the points, but the referee had his say with a couple of controversial decisions. Thanks for sticking with us today. Happy new year.
Full-time: West Ham 2 Norwich 1
... but it is cleared.
Norwich with a long throw into the box...
Agony for Norwich as the ball is pumped forward but play is halted by the linesman's flag for offside. 90 seconds to go...
Norwich give themselves hope as Elliott Bennett's right-wing cross is swept home into the near-post corner by Martin. Fine strike.
Goal! West Ham 2 Norwich 1 (Russell Martin)
Final change for West Ham as Jordan Spence replaces Matt Jarvis.
Opportunity for Fox on the edge of the box as the ball is half-cleared to him in space, but he could keep his half-volley down and the ball flew harmlessly over.
Decent chance for West Ham as they win a corner on the right that Cole gets his head to, but he couldn't quite divert his effort the right side of the post.
Change for Norwich as David Fox replaces Jonny Howson.
Change for West Ham as Modibo Maiga replaces Vaz Te.
West Ham look like they're happy to defend their lead now. One bank of four and then another bank of five are sitting deep and defending the box, with just Cole remaining in an advanced position. They're operating on the counter now.
More pressure from Norwich but they couldn't conjure a clean-cut chance and, in the end, Tettey is forced to let fly from 25 yards but sees his shot rise high over the bar.
More pressure from Norwich as Elliott Bennett darts down the right and wins a corner, from which Cole puts thousands of West Ham hearts in mouths by slicing a clearance back towards goal. Fortunately for the striker, Turner couldn't divert his header goalwards.
Norwich raid down the right in numbers down the right as Jonny Howson releases Martin, but Reid was there to clear his low cross. Immediately after, Jaaskelainen made a solid save from a low Snodgrass shot from the edge of the box. Now it's Norwich who ate cranking up the pressure.
Change for West Ham now as Gary O'Neill replaces Joey O'Brien.
Double-change for Norwich as Simeon Jackson replaces Kane and Elliott Bennett goes on for Hoolahan.
Scare for West Ham now as Ryan Bennett launches a long throw into the box from the right and West Ham's Reid diverts a header only just wide of his own post. From the resulting corner, Turner headed over from eight yards but was under severe pressure, so can't be blamed for missing the target.
Free-kick for West Ham from a dangerous position 25 yards out, slightly right of centre, but Taylor's strike hits the wall. Disappointing from a player who can do a lot better than that.
West Ham hit the post! Brilliant delivery from the left from Taylor and Vaz Te cushions a beauty of a header against the outside of the woodwork with Bunn well beaten. West Ham looking the more likely to score now.
Andrew Braybrook e-mails to say: "I hope west ham can at least make this game safe now, in are recent run of games we've just thrown it away again and again so the three points would be a great way to start off 2013."
Tremendous chance for West Ham but a corner from the right is missed by both Cole and Collison from close range. Big scare for Norwich.
Norwich attack down the left and Pilkington sweeps a menacing ball into the box that was begging to nodded home, but Reid rose high to make a crucial clearance. Straight back down the other end, Noble sees a shot from the edge of the box deflected over.
Norwich are seeing a lot more of the ball but West Ham aren't about to let their grip of this game go and are competing furiously in midfield to make life difficult for the visitors. Apologies for the cliche, but the next goal will be vital. If West Ham score it, the belief will sap out of Norwich. But if the visitors get it, nerves and doubt will no doubt set in for West Ham. Crucial 10-15 minutes coming up.
Glenn Robson tweets to say: "People need to lay off the referees they even themselves out over the season and it seems that only their mistakes mentioned."
West Ham hit back now and only a sharpish clearance from Russell Martin denies Collison what would have been a point-blank header on goal at the near post from a corner.
Jordan Neave e-mails to say: "Yet again Clattenburg.. Where's the Canaries penalty? Also Pilks was miles on side."
Norwich are also looking more positive and Snodgrass plays Pilkington though on goal, but the linesman's flag goes up for offside. He was definitely onside, but it didn't matter because Pilkington's shot was saved by Jaaskelainen. Promising for Norwich that they cut through West Ham so easily, though.
Another penalty shout for Norwich is waved away as Tomkins makes slight contact with Kane, who goes to ground, but Clattenburg isn't interested. It was 50/50 - it would have been both harsh and justified in equal measure either way. Incidentally, Clattenburg didn't book Kane for diving.
West Ham have started this second half as they ended the first: on the front foot. This has been a really positive, attacking display from Allardyce's side so far. Full credit to them for their approach.
Norwich win a free-kick in a tasty position on the right wing but, in their eagerness to convert Snodgrass' cross, several yellow shirts edge offside and West Ham are let off the hook.
Cameron Doran e-mails to say: "Norwich definitely don't deserve the current score line. Clattenburg has been awful, just like he is at any game, and Norwich have had majority of the decisions against them! Inquiry should be launched soon into Clattenburg's work, as it is not just this game which he seems to have messed up almost every decision!"
And we're back under way. Hughton needs a huge response from his team, but it's West Ham who are straight back on the attack.
Mike Hodgson e-mails to say: "Hoping we get another goal or two after the break, because we tend to slip up and lose our lead. We need a boost after the few losses we've just had."
The teams are back out, so we're only a few minutes away from the restart now.
I've just seen a replay of Hughton's reaction to the West Ham penalty decision. Let's just say it was easy to lip-read what he said and that it didn't make for family viewing.
Richard Skerritt e-mails to say: "A dubious penalty to West Ham, a dead cert for Norwich not given and West Ham's second goal whilst Tettey down with a head injury. Clattenburg should be subbed at half time. Dreadful ref who needs resting again."
So, West Ham deservedly lead after dominating the last half-hour of that opening period, but both their goals were extremely contentious and, really, neither should have stood. What are your thoughts? Does Chris Hughton need to make changes? Can Norwich get back into this? E-mail what's on your mind to email@example.com or tweet me @MattSkyCycling
Half-time: West Ham 2 Norwich 0
Finally Norwich get into the final third and create a space for a shot, but Tettey's 20-yard strike was well blocked by Tomkins.
West Ham are still seeing all of the ball but they have lost their forward momentum. But as I write, Noble collects the ball from Cole 22 yards out and he lets a right-foot shot fly that Bunn does well to tip over. From the resulting corner, Vaz Te's sliced a volley hopelessly wide from ten yards out. Should have hit the target.
Norwich are really struggling to mount any sort of attack now. They look like a team who have had a man sent off and are really missing the presence of Grant Holt and/or Steve Morison. West Ham are dominating both possession and territory.
Jordan Neave e-mails to say: "Really do not know what is going on with referees and Norwich at the moment. Norwich don't deserve this scoreline and I hope somebody shows Clattenburg the playback at half time because he needs to step up his game if he's going to be determining big Premier League results like these."
Cole misses from two yards out! Right on cue, Noble threaded a divine ball down the right flank to Demel, who flashed a low cross to the back post, where Cole scooped it over with the goal gaping. That was just as bad a miss as Vaz Te's header at the weekend. Massive let-off for Norwich, who need to get in at the break with the score as it is.
You wouldn't know Kevin Nolan is missing because Noble is controlling this match for West Ham. He is literally everywhere.
That second goal seems to have really hurt Norwich's confidence here. All of a sudden they're looking stretched at the back and the midfielders just aren't getting on the ball and retaining possession. All West Ham right now/
Brilliant effort from West Ham's Matt Taylor as Mark Noble collects a short corner on the left and cuts back to the former Bolton man, who sees a rasping left-footer tipped over by the excellent Bunn.
This is a very harsh scoreline for Norwich, who have come under plenty of pressure but don't deserve to be 2-0 down. They do need to get more men forward when they attack, though, because Kane is looking lonely.
Another contentious decision as West Ham score despite Norwich's Tettey being down on the ground with what looked like a head injury. Noble got to the left byline and crossed low, Bassong stabbed it away but O'Brien followed up and sidefooted home at the near post. Tettey was still down as West Ham celebrated.
Goal! West Ham 2 Norwich (Joey O'Brien)
Fantastic chance for West Ham as Jack Collison prods a seven-yard shot goalwards after a cross from the right from Guy Demel, but Bunn got down brilliantly to stop it and Ryan Bennett hoofed clear the scraps. Brilliant save.
Chance for West Ham as Ricardo Vaz Te lines up an overhead kick after a long ball into the box, but he almost took Michael Turner's head off and the free-kick was rightly given.
Norwich denied a clear penalty as Reid handles the ball with his fist under pressure from Bassong, but Clattenburg waves play on. It definitely should have been one penalty each.
Norwich hit the post! Snodgrass rattles a sublimely struck free-kick from 25 yards out against Jussi Jaaskelainen's left-hand post. That was a beautiful, curling left-footer. The keeper was well beaten.
This hasn't been the fastest-paced Premier League game I've seen this season - that much is for sure. Security at the back certainly appears to be Norwich's top priority, and to be fair, they're doing a pretty decent job of it so far. All of West Ham's play is going down Jarvis on the left-hand side.
Another decent opportunity for West Ham as Cole beats Ryan Bennett on the West Ham left and whips in a dangerous cross, but Michael Turner was alert and made a superb headed clearance. West Ham are getting on top now.
Katy Bingham e-mails to say: "Please let west ham win. Its my son's first game at Upton Park."
Chance at the other end now as Cole rolls Sebastien Bassong a tad too easily and launches a right-foot shot from the edge of the box that was on target, but Bunn was right behind it.
Hoolahan escapes from the West Ham midfield and charges forward, but his through-ball to Anthony Pilkington was under-hit and the opportunity was lost. It's been an even game other than the goal.
Cole hobbles back on but not without a real grimace on his face. He seems to be moving OK, though.
Momentary break in play as Carlton Cole goes to ground after a mid-air collision with Alexander Tettey. He's back on his feet but is limping heavily. Concern for Big Sam.
Norwich have responded well to going behind and West Ham defender James Tomkins has just had to make a desperate clearance to steer a menacing Robert Snodgrass cross away from danger.
William Spearing e-mails to say: "Hoping West Ham start the new year with a win, possible, but without Diame we are struggling and if we lose I can see the start of a rot. Going 2-1 to Norwich, but hope I'm wrong!"
The referee today, incidentally, is Mark Clattenburg, whose performance in the Stoke v Southampton match at the weekend was far from spotless. Chris Hughton certainly won't be pleased with him.
Mark Noble makes no mistake from 12 yards, sending Mark Bunn the wrong way with a crisp right-foot strike.
Goal! West Ham 1 Norwich 0 (Mark Noble pen)
Penalty to West Ham! Given against Ryan Bennett for shirt-pulling on Winston Reid. Looked harsh.
We're under way at Upton Park, with West Ham in their traditional claret and blue and Norwich in yellow.
The teams are on their way out at Upton Park and we are just a couple of minutes away from kick-off now.
If Norwich lose today, it will be the first time since April 2005 that they have lost four league games in a row. Fact.
If Norwich have done their homework properly, they will know it is worthwhile getting off to a flying start against West Ham. No team has conceded more goals in the opening 15 minutes of Premier League games this season than Sam Allardyce's side (seven).
Bunn, Martin, Bassong, Turner, R Bennett, Snodgrass, Howson, Tettey, Pilkington, Hoolahan, Kane. Subs: Rudd, Barnett, E Bennett, Tierney, Fox, Smith, Jackson.
West Ham team
Jaaskelainen, Demel, Reid, Tomkins, O'Brien, Noble, Collison, Taylor, Jarvis, Vaz Te, Cole. Subs: Spiegel, Spence, Diarra, O'Neil, Lletget, Lee, Maiga.
There's no Kevin Nolan for the hosts today but Ricardo Vaz Te comes in to make his first start since October. Norwich are also missing key men up front, with Grant Holt and Steve Morison both absent, so Harry Kane is brought in by manager Chris Hughton. Full teams to follow...
