Blues leave it late
Juan Mata scored a dramatic 93rd-minute winner as Chelsea enjoyed another huge slice of luck to beat Wigan 2-1 and move to within touching distance of the Barclays Premier League top four.
The visitors looked certain to climb out of the relegation zone for the first time for almost four months when Mohamed Diame scored a spectacular equaliser eight minutes from time.
A draw would have been no more than Wigan deserved after Branislav Ivanovic had put Chelsea ahead from an offside position just after the hour mark, but Mata won it at the death.
It was a disjointed opening 19 minutes by much-changed Chelsea, who finally tested Ali Al-Habsi when Gary Cahill let fly from 30 yards and the goalkeeper tipped over.
Both sides had half-hearted penalty appeals but the Blues were doing nothing to worry Champions League semi-final opponents Barcelona.
In the 38th minute Mata played a one-two with Didier Drogba who cut inside and shot straight at Al-Habsi. The rebound fell to Drogba but his header was cleared off the line.
Chelsea showed little improvement after the restart. The home fans were almost rewarded when Mata's sublime dinked ball found Drogba, who was again thwarted by Al-Habsi.
Shaun Maloney was cautioned for a challenge on Ivanovic, who made him pay from the free-kick with a 62nd-minute opener that should have been disallowed. Wigan thought they had cleared the danger but Raul Meireles played the ball back in to an offside Ivanovic, who steered it home.
Ivanovic was the Chelsea hero again seconds later when he blocked Franco Di Santo's shot on the line.
Wigan equalised with eight minutes remaining, Diame easily drifting past Ryan Bertrand and crashing an unstoppable shot home. Mata snatched it in the 93rd minute when Fernando Torres brilliantly volleyed Drogba's cross against the post and his fellow Spaniard bundled home.
