The Gunners beat Crystal Palace 2-1 in a tight clash at the Emirates Stadium.
Wojciech Szczesny - 6.5/10
Beaten from a set-piece during the first half but coped well in the second when Arsenal pushed for their winner.
Mathieu Debuchy - 7/10
A solid display from the Frenchman on his Premier League debut for the Gunners. Was almost beaten too easily by Yannick Bolasie at one stage but coped well otherwise. Had his shot blocked into Aaron Ramsey's path for the winner.
Laurent Koscielny - 7/10
His side's first-half saviour after netting Arsenal's equaliser from a set-piece. Was one of his side's most solid defenders on the day, as well.
Calum Chambers - 7/10
Like Debuchy, fared well on his competitive Gunners debut. Chambers will grow with time and is deputising well for Per Mertesacker considering he has only just moved to north London.
Kieran Gibbs - 6.5/10
Came off injured in the second half without lighting any fires during his time on the pitch but proved reasonably solid.
Mikel Arteta - 6/10
Arsenal may have taken the three points against Crystal Palace but they did not go without their struggles. A constant complaint was that they lacked imagination and, for that, their captain will have to take some of the blame.
Aaron Ramsey - 8/10
Was not his usual self in the first half but, at the end of the day, popped up to win all three points for his side. Already, the Welshman is proving a matchwinner for Arsene Wenger - and that should continue throughout the season.
Jack Wilshere - 5/10
Was completely outshone by Ramsey and, at this crucial juncture in his Arsenal career, does not look as though he can find any form for love nor money.
Santi Cazorla - 5/10
Like Wilshere, struggled to influence the game but not for a lack of trying. Indeed, the Spaniard often tried too much, taking on an extra man and being too adventurous with his passing. In the end, he was sloppy - in stark contrast to his impressive display during the Community Shield.
Alexis Sanchez - 7.5/10
Still looks to be missing a final product, with several crosses and shots just not doing enough. However, the Chilean was a constant threat in terms of build-up play, even though he lost Brede Hangeland for Palace's goal. There is, of course, an argument to suggest he should never have been marking him in the first place.
Yaya Sanogo - 5/10
Many were puzzled by Wenger's decision to start Sanogo and their questions came no closer to being answered after a poor display from the 21-year-old.
Nacho Monreal - 6.5/10
Did reasonably well after replacing Gibbs.
Alex Oxlade-Chamberlain - 6/10
His energy made a huge difference - but his final product did not. His passing was far too astray.
Olivier Giroud - 7/10
Much like in the Community Shield, Giroud's impact on the field was notable and the Gunners look a better side with him in the team, although many are still calling for a new striker.
