"London Calling" blasts out over the PA as we head towards today's clash...
So how are Hammers and Baggies fans feeling about this one? Drop me a line at email@example.com, or @TimOscroft on Twitter, and let me know where in the world you are tuning in from.
Peter Odemwingie's Twitter outbursts have earned the ire of manager Steve Clarke, but the controversial striker is on the Baggies bench today.
Those four successive draws between the two clubs followed West Brom's 3-2 win in September 2008, and such is the turnover in players these days that Brunt and Olsson are the only "survivors" in today's starting lineups that started that day, with Brunt bagging the winner in the 83rd minute.
West Ham are being well backed and have consequently been cut to 11/10 with West Brom drifting out to 12/5. However, this fixture has ended as a draw in its last four instalments, a trend which is 12/5 to continue. If you fancy a flutter on today's game, pop over to our friends at www.skybet.com for these and other tempting prices.
Baggies fans will still harbour hopes of a place in Europe for the first time since 1981/82 - is that realistic? Let me know at firstname.lastname@example.org, or if Twitter is your thing, @TimOscroft.
Today is the first game at Upton Park since the confirmation of West Ham's move to the Olympic Stadium, which will happen at the start of the 2016/17 season. Premier League football is essential to that move, and a win for the Hammers today will go a long way to allay relegation fears for this campaign. While their form is not great, they look in better nick than a few of the teams below them.
Garry from Stafford: "I reckon 2-0 to West Brom - we have the stronger team and haven't sacked a manager this season, it's due!"
Two changes for the Baggies from their draw with Stoke - Graeme Dorrans and Shane Long replace James Morrison and Jerome Thomas. What do you think of those lineups? Tweet me @TimOscroft, or email email@example.com.
For the hosts, one change from the side that lost to Chelsea, with skipper Kevin Nolan back from a toe injury at the expense of Jack Collison. Joe Cole is not fit enough despite being thought to be close to a return from a month-long hamstring layoff.
West Ham: Jaaskelainen, Reid, O'Brien, Collins, Demel, Diame, O'Neil, Nolan, Jarvis, Carroll, Vaz Te. Subs: McCartney, Tomkins, C.Cole, Collison, Henderson, Taylor, Chamakh
West Brom: Foster; Jones, McAuley, Olsson, Ridgewell; Dorrans, Yacob, Mulumbu, Brunt; Lukaku, Long. Subs: Myhill (gk); Odemwingie, Fortune, Thomas, Rosenberg, Popov, Tamas.
