Arsenal boss Arsene Wenger hailed Theo Walcott's performance for victory over Chelsea.
Walcott scored in his 350th game for the club.
Wenger said: "I think you cannot question his performance.
"I believe more the chance of Theo Walcott is his attitude this season. He's ready to fight, commit and you know that straightaway he gets the crowd behind him. Theo Walcott of that stature is a completely different player."
