Chelsea manager Maurizio Sarri has given up on Chelsea's title ambition as his questioned his player's attitude after the defeat at Wolves.

The Italian boss has now conceded to Pep Guardiola's side as champions ahead of the upcoming Premier League clash at the weekend with City at Stamford Bridge.
However, the former Napoli boss was not impressed with his players after letting in two goals within the space of four minutes.
The Italian, whose side slip to fourth, fumed: “Manchester City is in another category.
"We have to play and fight to be in the top four. It is very difficult the result for staying in the top four.
“For me City is the best team in Europe and maybe the best team in the world.”
Chelsea were up after 18th minutes through Ruben Loftus-Cheek but collapsed to defeat as Raul Jimenez and Diogo Jota scored in the 59th and 63rd minutes respectively.
Sarri added: “I think we played very well for 55 minutes.
“The first goal was an accident because we were in full control but suddenly we were another team.
“I am really very worried, not for the result, but the fact we didn't react to the first goal of the opponent.
“We didn't react at all and I am very worried for this. I have to understand why the team was suddenly another team.
“We were in control of the match. It wasn't a big problem. Then we lost everything - our football and the result.”
Sarri also insisted that the changes he made did not affect the outcome of the result: “I don't think it depends on the changes, it depends on the mentality of the team.”
And the 59-year-old suggested his side were too over-confident and may benefit from a reality check ahead of the showdown with City on Saturday.
He said: “After this match we lost confidence but maybe it is better because sometimes my players show me they have too much confidence.”
