Maurizio Sarri has expressed his concern over Chelsea's inability to react when Wolves equalised before going on to defeat to Blues at Molineux on Wednesday.
Chelsea looked to be in control of the game when Ruben Loftus-Cheek took the lead in the 18th minute, but Wolves hit back through Raul Jimenez and Diogo Jota to secure the three points.
Sarri believes his side had too much confidence during the game and he was at a loss as to explain why their performance dropped in the final 35 minutes.
"Of course, after this match we lost confidence but maybe it is better because sometimes my players show me they have too much confidence," Sarri said.
"It is more important to talk about our attitude after the first goal. We were not the same team as before, we were another team.
"Maybe it was important for the result but not for me. I have to understand why the team was suddenly another team because we were in control of the match.
"I thought we played very well for 55 minutes," Sarri added. "After the first goal, that was an accident because we were in control of the match, we were suddenly another team, without our distances and without our football. "
"I am very worried but not for the result, for the fact that we did not react to the first goal of the opponent. We didn't react at all so I am really very worried for this, not the result."
