Wolves fought back from a goal down to stun Chelsea and gain their first victory in seven Premier League matches.
The visitors went ahead when Ruben Loftus-Cheek’s 25-yard effort was headed into his own net by Wolves captain Conor Coady.
Chelsea had chances to extend their lead but Willian had a free-kick tipped over, Antonio Rudiger shot off target and N’Golo Kante fired just wide.
Those misses proved costly as Raul Jimenez’s low strike, following a fine run from 18-year-old midfielder Morgan Gibbs-White, made it level.
Wolves scored what proved to be the winner four minutes later as Matt Doherty’s cross was finished at the back post by Diogo Jota for his first Premier League goal.
It is now back-to-back away league defeats for Maurizio Sarri’s side, who drop down to fourth below Tottenham and remain 10 points behind leaders Manchester City, who they play at Stamford Bridge on Saturday.
