David de Gea: 7
Caught his crosses, made his saves, distributed the ball quickly and in accordance with the plan: a performance of quiet, Van der Sar-esque professionalism. No chance with the goal.
Alexander Buttner (off 73, injured): 5
One of those odd performances: never in the right place, never doing the right thing, and yet never making any serious mistake. Too often guilty, perhaps, of kicking the ball away blindly, but managed to avoid the shredding that Robben was supposed to inflict upon him.
Rio Ferdinand: 5
United's deep midfield suited the aging frames of Ferdinand and his partner, who were able to play the majority of the game with the ball in front of them. Generally tidy, he was comfortable enough until Mario Mandzukic peeled away from him and nodded the ball back to Bastian Schweinsteiger.
Nemanja Vidic: 7
As above, was helped by the strategy (or, if it wasn't a strategy, the mild air of retreat and panic). Marshalled a makeshift defence well and dealt capably with Thomas Muller, and though he wasn't marked for his goal, he still had to arc his neck and back and guide the ball with admirable precision. If this was his last time leading United out at Old Trafford in Europe, then it was a decent farewell.
Phil Jones: 6
One moment in the first half encapsulated Jones's United career: an excellent interception, then a fall to the floor, then a flailing attempt to hack the ball clear from the deck, which failed, yet managed to distract the onrushing striker enough to prevent disaster. Bless him. Ended up playing in both full-back positions, and just about managed to keep up with on both Robben and Ribery.
Ryan Giggs (off h/t): 5
Held his position well enough throughout the first half, though was clearly inhibited by injury as half-time approached. No real opportunity to play the raking passes that characterised his performance in the previous round.
Michael Carrick: 6
What ball United had he moved around neatly, and while he didn't always manage to track the runners from midfield, he did at least look to have shaken off some of the torpor that has marked his recent showings.
Marouane Fellaini: 3
Oh, Marouane. Being generous, the Belgian did an adequate job of getting in the way of Bayern Munich throughout. However, he was resolutely terrible in possession, stood and watched as Bastian Schweinsteiger clipped home Bayern's equaliser, and weirdly appeared to forget how to jump for headers. Would almost certainly have been withdrawn had injuries not flared up.
Antonio Valencia: 6
Energetic as ever, pacey as ever, frustratingly short on the wit that sets truly world-class wingers apart as ever. Provided good cover for Phil Jones before being moved to right-back, then stayed out of trouble thereafter. Certainly lucky not to be dismissed for a second yellow card, though perhaps should never have seen the first.
Danny Welbeck (sub 83'): 8 for most of the match, 2 for one split-second
Oh, Danny. Unlucky to be penalised for a high foot in the third minute, after which he finished excellently. Unwise to attempt to chip Manuel Neuer when clean through in the 39th minute. Those moments aside, though, he was selfless and utterly adorable as a roaming striker, and he never let Javi Martinez settle.
Wayne Rooney: 7
For all that he is a fundamentally unsuitable candidate to replace Vidic as captain, performances like this make you understand why a manager might be tempted. Utterly devoted to the busywork between midfield and Welbeck, and found the occasional moment of quality when the game allowed. Fine corner for Vidic's goal; gorgeous dive for Schwinsteiger's red card.
Shinji Kagawa (h/t for Giggs): 6
Many United fans would have liked to see Kagawa start, and it was suggested in commentary that he might well have done had defensive injuries not necessitated cover. Once introduced, however, he buzzed around effectively and contributed to a shaky night for Javi Martinez. Will have some role to play in the second leg.
Ashley Young (73m for Buttner) n/a
Some good running, some rubbish crossing.
Javier Hernandez (84m for Welbeck) n/a
Had exactly one opportunity to run into space behind the defence, and was fouled by Martinez before he could get away. The card will see the Spaniard suspended for the second leg, mind, so that's handy.
