Chelsea missed the chance to go top of the Premier League after a 0-0 draw at Everton on Sunday.
Enzo Maresca’s side had to settle for a goalless stalemate that ended their five-match winning run in the league.
Chelsea sit one point behind Liverpool who have two games in hand on the Blues.
“That was a real game. Everton are one of the best teams in Europe in terms of clean-sheets. We are very happy because this is a tough stadium, not only for us but also in the Premier League,” Maresca said.
It was an encouraging start to a new era for Everton — four points clear of the relegation zone — under new owners the Friedkin Group, whose purchase brought an end to Farhad Moshiri’s tumultuous tenure.
Wolves boss Vitor Pereira enjoyed a dream debut as his side won 3-0 at relegation rivals Leicester.
Replacing the sacked Gary O’Neil, Pereira made an immediate impact after leaving his role at Saudi Pro League side Al-Shabab.
Goncalo Guedes started the Pereira era with a flourish as he met Nelson Semedo’s cross with an agile finish in the 19th minute.
In the 36th minute, Rodrigo Gomes slid in to notch his first goal for Wolves before Matheus Cunha’s 44th minute strike ensured third-bottom Wolves would move within two points of fourth-bottom Leicester.
Bottom-of-the-table Southampton held on for a 0-0 draw at Fulham as new manager Ivan Juric watched from the stands.
Juric, axed by Roma in November after just 12 games, was not in charge on Sunday as he awaited a work permit to replace Russell Martin.
Southampton are eight points adrift of safety with only one win from 17 league games.
