Well, I'll analyse this from an Arsenal Perspective.
Almunia - Had a really good game, great character to come back from Saturday, and showed why some are tipping him for england.
Sagna/Eboue - The latter seemed to get better as the game went on, Sagna looked quite comfortable at right back, will be interesting to see if he was injured.
Clichy - Had great energy throughout, he really looks back to his best. He has some lapses of concentration, which if he can remove, he will be the best Left Back in a few years.
Vermaelen - Quiet game, good interceptions, and his great heading. Could say he was at fault for the second.
Gallas - Actually looked shaky, we looked more secure when Song slotted into Centre back.
Song - Wow, proved what I've been saying for weeks, quite simply world-class, whether at Centre Half or Holding-Mid, he is immense, strong, great tackles, and even showed a few good passes tonight.
Denilson - Arsenal's best second half performer, was great. Distribution is immaculate, and he really does make Arsenal tick.
Cesc - Clearly not 100%, but showed some drive in the second half.
Nasri - Played ok, showed glimpses of his class, but couldn't get enough of the ball.
Arsh - Not much to comment on.
Bendtner - Pretty much won most headers, good touches. Not enough support and not enough of the ball.
Walcott - Need I add anything? Great pace and dribbling.
If I get time, match analysis up later.
