MANCHESTER UNITED
David de Gea 6
Never really stretched but for a couple of decent punches, and the Spaniard's handling was sound when called upon
Chris Smalling 8
Excellent defensive display, especially in the second half. One wild cross, though, and might have scored with a header
Jonny Evans 7
Distribution was a couple of notches below the quality of his defending, notably in the first half, but a reliable presence
Nemanja Vidic 7
Decent, no-frills defending, doing well in the air against Giroud, but forced off at half-time with a head injury
Patrice Evra 6
The left-back was troubled by Sagna in the second half, with several crosses coming into United's box from his flank
Phil Jones 8
Fantastic first half in midfield, defending well and breaking at times, and good when pushed into central defence after that
Michael Carrick 6
Could not stem as much of the passing as he would have liked but calm, used the ball tidily and broke up play on occasion
Antonio Valencia 6
Involved only in little bursts but his pace occasionally stretched Arsenal and the winger provided a handful of dangerous crosses
Wayne Rooney 8
Muscular, non-stop effort. Not everything worked – he wasted a chance – but set up the goal and never allowed Arsenal any peace
Shinji Kagawa 5
Display of defensive hard work and useful simplicity rather than exhilaration, but faded as the match went on and was substituted
Robin van Persie 7
Well-taken header was the decisive moment against his former club. Much brighter in general play after the interval than before it
ARSENAL
Wojciech Szczesny 6
Could not be blamed for Van Persie's goal and was otherwise untroubled. Reliable when taking high balls
Bacary Sagna 8
Dangerous attacking presence after the interval, providing several good crosses from the right. Defended solidly
Thomas Vermaelen 7
Did well in his first Premier League start of the season, the central defender helping to restrict United from open play
Laurent Koscielny 6
Had to adjust to not having the ill Per Mertesacker with him. Defended decently but passing let him down at times
Kieran Gibbs 6
Did not have the impact of Sagna going forward and a mixed bag defensively. Van Persie's goal drifted over him
Mikel Arteta 7
Accurate passing helped Arsenal to dominate possession in the second half and broke up play at times, but no major influence
Mathieu Flamini 5
Looked the squad player many expected when he rejoined. Taken off, having been booked, as Arsenal sought more thrust
Aaron Ramsey 6
Failed to replicate his usual attacking menace but had two shots – one blocked, one weak – and drifted in search of the ball
Mesut Özil 4
Firing wide when given the chance to set someone up, or hit the target, summed up an underwhelming performance
Santi Cazorla 5
Another Arsenal player who failed to have the expected attacking influence, showing only flashes of his talent
Olivier Giroud 5
Hold-up and link play were below par, though he mostly lacked good support. Partly to blame – with Ramsey – for the goal
