Made a tremendous save on a powerful Lewandowski effort.
Dealt with the threat of Robben well, not allowing him to cut inside onto his left.
A great pass out of the back put Walcott through but he was torn apart for the third and turned it over for the fourth.
Shown a red card for hauling back Lewandowski in the area, which left his team a man down.
The full-back's crossing was poor, but he stretched the defence a lot in the first half.
Couldn't cope with the tenacity of Vidal the longer the game went on.
Some great runs, but he kept his head down far too often.
Offered nothing as an attacking option in midfield.
Fired Arsenal into an early lead but was wasteful with a handful of chances thereafter.
Restored to the starting lineup, but he was unable to make an impact.
He did play a role in the opener, but two glaring misses were more notable.
Walcott's finish was a blitz, but he still helped it on its way into the back of the net.
One mix up that allowed Giroud space aside, he was flawless.
Did his job at the back, and barely had a thing to worry him in the second half.
A pest out wide, nipping in to win possession and overlapping regularly.
He had real trouble defending his flank in the opening half, and was caught out for the goal.
The winger was having a frustrating game until he profited from poor defending to make it 2-1.
Played more of a supporting role on the night, not taking on his man too often.
A terrier in the middle as he was too much for Arsenal to handle, finishing twice in the second half past a defeated defence.
The midfielder pulled off an array of flicks and deft touches that had the opposition guessing.
Easy for him once Arsenal were a man down to set attacks in motion.
Buried the leveller from the spot and hit the post after that with a sliding finish.
