Chelsea went four points clear in the the English Premier League after they managed a 1-0 victory over Bolton thanks to a lone goal form Nicolas Anelka on Tuesday.

Anelka headed in the winner for Chelsea in 43rd minute against his former club to clinch a fourth straight league victory for Chelsea that keeps the FA Cup finalist on course for a double.

Chelsea can afford to lose one of its four remaining matches, which includes hosting Tottenham on Saturday and a trip to Liverpool, and still win its first English Premier League championship since 2006.

Manchester United were in second place, two ahead of Arsenal, who is six adrift in third place going into Wednesday's north London derby against Tottenham.
