An inspired Nicklas Bendtner ended Arsenal's goal drought as bottom-of-the-table West Brom were swept aside.

The Dane's left-foot shot opened the scoring and gave the Gunners their first goal in five league games but Chris Brunt equalised with a free-kick.

Kolo Toure restored the visitors' lead, heading in Andrey Arshavin's free-kick.

Bendtner made it 3-1 with a crisp volley and he later hit the foot of the post as Arsenal dominated and boosted their Champions League hopes.
