London - Aston Villa came from behind to stun Chelsea 3-1 at Stamford Bridge on Saturday and leave Andre Villas Boas' stuttering team outside the Premier League top four heading into 2012.
Didier Drogba gave the hosts the lead from the penalty spot in the 23rd minute after he was fouled by Richard Dunne, but the lead lasted only five minutes.
Stephen Ireland's first effort from Charles N'Zogbia's cross was blocked by John Terry but the midfielder tapped in the rebound to make it 1-1 at halftime.
With Chelsea fearing a fourth straight 1-1 draw, Stiliyan Petrov made matters worse when he put Villa ahead in the 83rd after being set up by Ciaran Clark and three minutes later, Darren Bent sealed his side's first win at Stamford Bridge since 2002.
