"It is hard to describe our performance, it's hard also to understand", Maurizio Sarri reflected, per BBC Sport.
And The Times report that Sarri is concerned he does not have the right players to successfully implement his style of play.
Sarri's players and the club were humiliated by the 6-0 drubbing against Pep Guardiola's City at the weekend and have been pushed out of the top four by Manchester United's resurgence under caretaker Ole Gunnar Solskjaer.
The Blues suffered their biggest ever defeat in the history of the Premier League after they were steamrolled by a rampant Manchester City at the Etihad on Sunday. The City striker capitalised on Chelsea's poor defending, and once again produced a performance to remember. "It's only halfway through Sarri's first season but the worst thing I can say is it looks like he has turned Chelsea into Arsenal".
"They are obviously a team bereft of confidence, now whether that is because they don't like the way they are playing or don't agree with the way they are playing, the players still have to go out and give more", Clement added.
Sarri is under pressure after some dismal results.
While a manager can not entirely be judged on his results in the first season, wherein he is still in the process of identifying his best side and stamping his authority at the new club, Sarri does need to turn things around quickly.
Carragher's criticism does make sense, with Chelsea often struggling to perform anywhere near their best levels on the road this season.
