Samir Nasri says he's a better player for making the move to Arsenal.

Nasri admits they cannot afford defeat at Chelsea tomorrow if they want to keep their title hopes alive.

And asked if he has improved working under manager Arsene Wenger, Nasri also told L'Equipe: "I have progressed in all areas.

"Tactically, I know how to play on one side even though I remain convinced that I can play better through the middle. I'm also defending a lot better.

"Technically, I'm much more fluid in the one-touch game. That wasn't the case at Marseille.

"My left foot has improved. And I'm also more of a shooter in front of goal."
