Drogba has now scored 13 goals in 13 matches against Arsenal
Arsenal paid the price for their failure to take the chances they created in periods of domination at Stamford Bridge - and for their continuing inability to contain Drogba as Carlo Ancelotti's champions stretched out a four-point lead over their title rivals.
Arsene Wenger's side came close through Marouane Chamakh and Laurent Koscielny, while Andrey Arshavin brought a superb save from Petr Cech before Drogba struck his 13th goal against The Gunners in as many games as the interval approach.
