A Pedro Neto 95th-minute strike gave Wolverhampton Wanderers a dramatic victory and stopped Chelsea from topping the Premier League table on Tuesday.
In-form Olivier Giroud had put the Blues ahead with a 49th minute strike culled from Ben Chilwell’s cross.
However, Daniel Podence scored the equalizer after tiptoeing through the Chelsea defence before wrong-footing goalkeeper Edouard Mendy with a shot that deflected in off Reece James.
Neto who was denied a penalty after referee Stuart Attwell reviewed his original decision on the pitch-side monitor on a possible foul by Reece, got another chance. And this time, he made it count and condemned Chelsea to a second successive premier league loss.
The Blues had lost 1-0 to Everton last week Saturday.
Meanwhile, Chelsea boss Frank Lampard has blamed his team’s recent poor run of form in fatigued and injury.
“There could be some fatigue,” said Lampard, whose side have already played five games in December.
“I hate to say it after a defeat because it feels like an excuse but even in the first 60 minutes when we were the better team, we didn’t have a zip about us.
“We’ve travelled up to Everton, came back and then travelled to Wolves but everyone is in the same boat.
“We have a couple of injuries in areas which means I can’t make too many changes so I understand that side of it.”
