In a furious encounter at Old Trafford, Manchester United got their 2012/13 Champions League campaign off to a winning start, thanks to an early strike from midfielder Michael Carrick.

The game will most likely be remebered though for the penalty call given, and the countless not by referee Wolfgang Stark as both times were left appealing in vain several times in the game.

Next up for Sir Alex's side is a potentially difficult trip to CFR Cluj, who somewhat surprisingly beat Braga 2-0 in the group's other clash.

Stay tuned to Bleacher Report for all the reaction from this, and the other Champs League games shortly.

90+5'- That's that from Old Trafford as Wolfgang Stark calls time on an eventful game.

90+3'- PENATLY SHOUT GALA!

Jonny Evans dithers in the United area before going in late on Yilmaz. No call from the referee again. We could have had four or five penalties, tonight.

Straight down the other end, Hernandez's bicycle kick flies miles over the bar. Should have done better there.

90+1'- CHANCE UNITED!

Nani feeds through Chicharito one-on-one again, but the Mexican striker hesitates, and his delicate shot is cleared by a retreating defender.

Five minutes to be added on here. Not sure if Galatasaray have the heart to threaten though.

Juventus smell victory at Stamford Bridge, with the score at 2-2. Nervous times for the Chelsea faithful.

88'- PENALTY SHOUT UNITED!

Valencia beats his man, then falls over theatrically in the area, but nothing doing.

87'- Rafael looks to wind down the clock in the corner.

Galatasaray almost look too tired to mount one last attack on the United goal.

85'- United make their last change as Danny Welbeck replaces Shinji Kagawa. Looks like the Red Devils will switch to a more standard 4-4-2, now.

Hernandez almost scores straight away, but shoots wide when put through one-on-one.

Barcelona have come from behind to lead 3-2 against Spartak Moscow.

Danny Welbeck preparing to come on here.

82'- Sustained spell of possession for Galatasaray as they increase the pressure on a fragile looking United. Yilmaz's cross drifts over

80'- Fletcher straight into the action as he wins the ball from Altintop.

Van Persie picks up a yellow card seconds later from a lunge on Elmander. He's then replaced by Javier Hernandez.

79'- Welcome back Darren Fletcher! He replaces a tired looking Paul Scholes.

The last time Darren Fletcher player for United, he scored, in a Champions League group stage game against Benfica.

78'- United really trying to kill this one off at the moment.

Kagawa's shot on the edge of the box is blocked yet again, before van Persie is unable to turn when the ball falls to him.

United's next Champions League game is an away trip to Romanian side CFR Cluj.

That's another potentially difficult tie for Sir Alex's side.

Uncomfortable viewing for United fans, as their 1-0 lead looks tenuous at best.

75'- Poor from van Persie.

It's three on two as Nani, Kagawa and van Persie break. Nani puts in the Dutchman, but his first touch is poor and the chance is gone.

73'- This one has really livened up in the last few minutes as van Persie has a shot blocked.

The Dutchman has been mostly ineffective so far tonight, not sure why he didn't take the earlier penalty.

72'- CHANCE GALA!

Crazy as Nani dives in the Galatasaray area, the Turkish side break quickly before David de Gea saves well twice in quick succession.

Replays show Nani may have had a point there.

71'- CHANCE EVRA!

Nani plays an excellent through ball to the on-rushing Patrice Evra, who holds off a challenge, before seeing his shot saved by Muslera.

3 - Man Utd have already missed as many penalties this season as they did in the whole of 2011/12 (all comps). Spurned

68'- Galatasaray stroke it around the periphery of the United box, before Elmader slips when fed through.

The Red Devils again unable to counter effectively, though.

66'- A break in play as Eboue goes down hurt.

If Gala score late tonight, what's the betting on Fatih Terim celebrating like Mourinho?

Even if Utd win this, their will be a hairdyer with Nani's name on it when he gets back to the changing rooms after that peno #bbcfootball

The Reds have lost only two of their last 56 Champions League games at home (AC Milan and Besiktas).

64'- Both sides really struggling to keep possession at the moment.

The longer this one remains 1-0, the more Galatasaray will fancy getting a result.
