Arsene Wenger praises 'convincing' Arsenal win

Manager Arsene Wenger says Arsenal still need to "convince" their critics they are capable of winning the title after a 3-1 victory over West Ham.

Wenger describes his side's victory as a "convincing performance" and singles out Cazorla as a "delight" to watch after the Spaniard scored Arsenal's third with a stunning longe-range strike.

Olivier Giroud and Theo Walcott were also on target for the Gunners after West Ham's Mohamed Diame had put the home side infront on 21 minutes.
