LONDON — Arsenal overwhelmed defending Premier League champion Chelsea 3-1 on Monday to keep the pressure on first place Manchester United in the title race.
Alex Song, Cesc Fabregas and Theo Walcott scored for Arsenal in a 10-minute span split by halftime.
Despite Branislav Ivanovic's goal with a 57th-minute header, Chelsea couldn't come back against a team it had beaten in their last five matchups.
The loss compounds the problems facing manager Carlo Ancelotti, whose side began the season with five straight wins but has now failed to win in the league since Nov. 10.
Arsenal, which hadn't scored a goal against Chelsea since May 2009, last beat the Blues in November 2008.
