Branislav Ivanovic scored in the 31st minute, and Chelsea neutralized the Premier League's most potent attack with a 1-0 win at Manchester City on Monday night.
Ivanovic scored on a 25-yard shot, and the Blues ended Manchester City's streak of 61 home matches since November 2010 in which it had scored. Chelsea also hit the goal frame three times.
Arsenal (17-3-4) regained the Premier League lead on Sunday and is two points in front of City (17-5-2), which is ahead of Chelsea (16-3-5) on goal difference.
City has 115 goals in all competitions and had been 11-0 at home in the league this season.
