Wolves boss Nuno Espirito Santo challenged his side to “maintain these standards” after they fought back from a goal down to stun Chelsea and gain their first victory in seven Premier League matches.
Two goals in four second-half minutes – from Raul Jimenez and Diogo Jota – gave the hosts victory after Ruben Loftus-Cheek’s 25-yard effort was headed into his own net by Wolves captain Conor Coady after only 18 minutes.
“This doesn’t mean all the problems are solved,” said Nuno, whose side won for the first time since their 1-0 away victory at Crystal Palace on 6 October.
“It was a very good performance. In the first half, the organisation and staying in the game was important.
“In the second half, we showed desire to go in front. It was fantastic work from the boys. The only way to play these teams is you have to run more than them and when you have your chances take them. We have to maintain these standards.”
Wolves’ win leaves them 12th in the Premier League, only four points behind sixth-placed Everton.
Chelsea had 70% possession and 17 attempts but suffered back-to-back away league defeats despite dominating the first half.
“Of course I’m disappointed,” said Blues boss Maurizio Sarri. “We played very well in the first half and could have killed the game.
“Suddenly we conceded a goal and we were not the same team. It’s very difficult for me to understand why – I can’t understand the reaction.
“We played very well for 55 minutes and then suddenly we were another team.”
After Chelsea’s goal, they 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 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 Jota for his first Premier League goal.
Sarri’s side drop down to fourth below Tottenham and remain 10 points behind leaders Manchester City, who they play at Stamford Bridge on Saturday.
