Crystal Palace 0-2 Arsenal: Wenger praises 'mature' Arsenal

Manager Arsene Wenger praises a "mature" performance as Arsenal win 2-0 away at Crystal Palace despite Mikel Arteta's sending off.

Having put the Gunners in front from the spot, Arteta was dismissed for a professional foul on former Gunner Marouane Chamakh, before Aaron Ramsey set up Olivier Giroud to seal victory late on.

Wenger also praises a "better focused" Wojciech Szczesny - who made a crucial second-half save - as Arsenal maintained their lead at the top of the Premier League.
