Wolverhampton Wanderers’ hard-fought victory helped allay their relegation concerns, while Frank Lampard lost on his return to the Chelsea bench.
Upon his appointment as interim head coach at Molineux 18 months after being fired from the position, Chelsea great Lampard was met with an enthusiastic ovation by the visiting supporters.
Yet the club’s all-time record scorer was unable to stop the poor form that led to Graham Potter’s sacking as mid-table Chelsea slumped to an 11th top-flight defeat of the season after failing to score for the third successive game.
Wolves were on the front-foot throughout and deserved their win which came after a sweet finish by Matheus Nunes, the Portugal midfielder’s first goal for the club since joining from Sporting Lisbon last August.
Nunes, who cost a club record £38m, beat Kepa Arrizabalaga with a fierce attempt from the tightest of angles after an attempted headed clearance by Kalidou Koulibaly.
Joao Felix forced a save from Jose Sa but Chelsea were disappointing and remain 11th after just two wins in 11 league games.
