Former Chelsea defender Frank Leboeuf has slammed four players of the club.
He also criticised record summer signing Moises Caicedo.
Caicedo has started life at Stamford Bridge poorly, giving away a penalty on his Chelsea debut.
The Ecuadorian was also largely at fault for Nottingham Forest’s goal in their shock 1-0 win at Stamford Bridge last weekend.
Leboeuf noted that Caicedo and Enzo Fernandez are struggling with confidence in the Chelsea midfielder.
He said that lack of confidence is making them only ‘do the minimum’.
Leboeuf is not also happy with the performances of Thiago Silva and Axel Disasi.
“I think it’s a matter of confidence for the Chelsea players but also how you make them play and how you can turn and twist their brain,” Leboeuf told ESPN.
“It’s not that they’re not good players, but they don’t know what to do.
“The only thing they think is, ‘I don’t want to lose the ball’ – which is why we see Enzo Fernandez and Moises Caicedo and some others not taking any risks.
“They don’t want to be booed and they don’t want to be criticised so they do the minimum. That’s the thing.
“I was getting a little bit upset with Thiago Silva and Axel Disasi because they don’t take enough risks.
“They should go [forward] and outnumber [the opposition] but they don’t do that, it’s too simple and it doesn’t work.”
