Arsenal midfielder Santi Cazorla says they have the squad to compete for the title.
The Gunners look challengers after an impressive start to the season.
Cazorla said: "Arsenal haven't won anything for many years but I believe the club always show passion and are a team of winners.
"This is almost an entirely new team, the boss has made lots of changes by bringing in Lukas Podolski, Olivier Giroud, Gervinho and Alex Oxlade-Chamberlain. They are all good players and we are still missing Jack Wilshere and Tomas Rosicky.
"We have a good squad and are optimistic."
