The Blues boss was perplexed as his side threw away a lead to lose to Wolves, insisting they should have "killed the game" in the first half
Maurizio Sarri was left "very worried" by Chelsea's response to conceding the equaliser in their 2-1 defeat at Wolves on Wednesday.
Ruben Loftus-Cheek gave the visitors an early lead, but Raul Jimenez pulled Wolves level at the hour mark and the home team went ahead four minutes later through Diogo Jota.
Sarri was pleased with the way his side started the game but felt it all hinged on their attitude following Jimenez's goal.
