Maurizio Sarri questioned his ability to motivate Chelsea's spluttering stars after their humiliating 4-0 defeat at Bournemouth on Wednesday.
The shocking result at Dean Court ranked as Chelsea's biggest league defeat for 22 years and was their fifth loss in the last 12 Premier League games.
Chelsea boss Sarri maintained he does not feel under pressure but admitted the blame for the defeat could lie with himself.
"I needed to understand. It's impossible to play in such a different way between the first and second half.
"I think [the players are good enough]. We cannot lose 4-0 against Bourne-mouth. Maybe it's my fault, maybe I'm not able to motivate them. But the team is very strong, it is also able to win without the coach."
"I feel frustrated. I didn't see the signal of my work."
