(CNN) -- Chelsea's chances of retaining the English Premier League title suffered another setback on Sunday as struggling Aston Villa snatched a last-gasp 3-3 draw in London.
Carlo Ancelotti's team had fought back to lead 3-2 with two goals in the last 10 minutes, but poor defending allowed young Villa fullback Ciaran Clark to equalize with a free header in the second minute of time added on.
The result left Chelsea in fifth place, a point behind Tottenham and six adrift of the leading Manchester clubs United and City.
The Blues ended 2010 with a morale-boosting win over Bolton last Wednesday, and looked like extending that form when Frank Lampard scored his first goal since returning from long-term injury in the 23rd minute. CNN
