Arsenal finally ended their barren run of form against Premier League champions Chelsea with an impressive 3-1 victory at the Emirates. 

So often have the Blues tormented their London rivals in recent season but Carlo Ancelotti's men were pegged back for the most part in an evening where the Gunners turned their possession into goals.

Alex Song broke the deadlock just before half-time, stroking home from inside the area to give the home side the lead at the break.

Arsene Wenger sent his troops out firing as the excellent Theo Walcott picked out Cesc Fabregas to sweep home the second six minutes after the restart, and the captain returned the favour to send Walcott through to finish emphatically for the third.

Branislav Ivanovic headed a consolation and while there was a momentary period of pressure, Chelsea limped to yet another defeat to leave them with just three points from six games.
