FULL TIME. Galatasaray 1 Manchester United 0.
Yilmaz heads off to a warm applause as Bulut takes his place.
Hernandez and Cleverley combine, with the former eventually shooting from just inside the penalty area, the Gala bodies getting in the way to ensure a safe save for Muslera.
Hernandez looks to pounce after a Kaya slip, but Eboue desperately hacks clear, taking a knock in the process from Young.
Melo is next to test Lindegaard's gloves, and while it's a powerful effort, it's straight down the throat of the United keeper.
Buttner finds Young behind Eboue, and the winger takes him on, falling under his tackle where no foul is given.
Hernandez challenges Muslera from Buttner's ball, but United really look devoid of any invention in the final third now and this game really should be Galatasaray's for the taking.
Welbeck heads off as King makes his CL debut for United.
Welbeck loses out after trying to force his way into a shooting position, and the hosts take this opportunity to kill some time with some neat passing.

Yilmaz goes into the referee's book for what the referee believes is simulation during a clash with Jones.
Inan's free-kick looked to have clipped the head of Baytar, and it sails out of play for a goal-kick despite the striker claiming the ball touched a United head.
Can Manchester United do what they do best and comeback and win? They're 20/1 for victory now with a draw 7/2.
Young and Macheda replace Powell and Anderson in a double United swap.
Welbeck puts the pressure on Muslera, something the Gala defence isn't too happy about, but he was entitled to go for the ball and a free-kick alone is the right decision.
Altintop cuts inside Buttner, taking a pop which is cleared away by Carrick, as United are put on the back foot for the time being.
The stretcher is taken off, fortunately without Inan on it, and the midfielder looks fit to continue now as he tries to walk off the injury.
Inan collides with Cleverley and the stretcher is on for the Gala man as it looks like his game it set to come to an end.
Free-kick to United as Amrabat slides in on Rafael, but the hosts are well organised as they force United back with Nounkeu intercepting Anderson's through ball.

Elmander is taken off for Gala, with Baytar the man replacing him.
Two clearances from Melo result in two more corners, the first two deliveries quite poor from Anderson. His third is no better and cleared easily by Amrabat.

Inan's powerful drive cannons off Carrick and again United break, with Hernandez drawing a brilliant save from Muslera as the visitors win a corner.
Riera's cross to the back post is headed clear by Cleverley, and United look to break with Powell, who is tripped down the right by Nounkeu.

Amrabat crosses in as Gala press for a second, but Yilmaz is dealt with strongly by Buttner as the left-back ushers the ball out of play.
This time though, Man United are undone as Yilmaz pounces from the corner with a header that finds the top corner and leaves Lindegaard grasping at air. 1-0 to the hosts!
GOAL FOR GALATASARAY - YILMAZ!
Eboue's powerful drive clips Jones' head, before Melo's fierce header is tipped over the bar by Lindegaard.
Anderson's divine turn takes him away from Melo, but he can't force forward into the box, and in the end Hernandez is blocked off well by Riera with the result a goal-kick.

Riera does well to control the ball and then unleash a good shot that results in an impressive display of handling from Lindegaard.

Pete Shields writes: "Man U always look a bit weak up front without Rooney and Van Persie. However, I think if Young and Macheda come on they could get a couple."

One minute of added time to be played.
Riera crosses in a curling ball from the left, but United's makeshift centre-back partnership continue to look strong as Jones calmly heads away.
United look much more threatening now as Rafael link up with Anderson, the latter eventually losing out to Riera after a tackle that could easily have resulted in a United free-kick.
Welbeck shows wonderful drive to force a corner, and from the delivery Powell powers a header against the crossbar! So close to a goal on his Champions League debut.

Carrick does well to hack away the corner, but Altintop picks up the ball and spreads play to Amrabat who is forced back by solid play from Fletcher.

Gala break from United's dreadful free-kick, and Amrabat collides with Rafael, no penalty given before Lindegaard eventually grabs the ball out of the air.
Another foul, and this time it's Melo on Cleverley. United win a free-kick 30 yards out, but it's a poor routine that sees Fletcher give the ball away.
Powell concedes a foul on Melo, but while things aren't going to well for the youngster defensively, he does look a threatening cog when United march forward.
Powell's touch allows Melo in to intercept, but terrific hussling from Cleverley wins the ball back for United as they knock the ball around the centre of the pitch.
Amribat makes progress down the left, until Carrick steps in, but United fail to retain possession and it's right back with the hosts.
Riera looks for Yilmaz, and eventually his ball is collected, before Amribat goes for goal from range, with a deflection carrying the ball into Lindegaard.
Lovely movement from United, with only a poor final pass from Powell into Rafael bringing it to an end. The visitors' best move of the match so far.
Inan's ball in is a good one but Yilmaz, unmarked, can only head over from close range and spurn the first real chance of the game.
Yellow card for Rafael after the full-back makes an ill-advised tackle on Amrabat near the touchline.

Altintop slides in on Welbeck, taking the striker's studs to his front in the process and understandably wincing in pain.

Eboue's loose touch allows United to regain possession, but a crunching tackle from Kaya on Powell results in an early booking.

Rafael is tripped on the touchline by Inan, and much to the home man's chagrin, a foul is given in United's favour.

Phil Hoole writes: "Greetings from Iowa USA. I am curious to see where the width is coming from. I see a 1-1 draw."
Ben Gleeson writes: "Very happy that Powell is playing tonight, I've wanted him to get more starts in the league, mainly because he is not afraid to hit shots outside the box. That is just something United don't do enough of anymore, Rooney used to do it a lot, but now it's all crosses and too much passing. Excited to see some 25 yarders fly in. 3-1 to United."
Iacovos from Cyprus believes the: "Key battle tonight is Carrick vs Elmander. Let's see if Elmander will do a 'Fellaini' over Carrick tonight...

The Turkish champions are evens to pick up their second win of the campaign, with the draw (11/4) not fancied by many ahead of kick-off.

And here are the teams in full...
Some early news is that Phil Jones makes his first Manchester United appearance of the season and Nick Powell his first start. Powell's introduction is Sir Alex Ferguson's only concession to youth, but his bench is packed with it, underlining United's status as group winners with two games remaining. Former Bolton front-man Johan Elmander is included for the hosts, along with Premier League old-boys Albert Riera and Emmanuel Eboue.
