Chelsea goalkeeper Petr Cech earned the backing of interim head coach Guus Hiddink after another nervy display in the thrilling 4-4 Champions League draw with Liverpool.
The Czech Republic international has looked short on confidence in recent weeks and was again at fault for at least one of the Reds' goals at Stamford Bridge.
However, Hiddink said after the game: "He is a very intelligent and self-critical goalkeeper.
"He was not happy with his performance against Bolton, although there was always a sequence of errors before he came into action.
"But he is very critical of his own performance even when he has had an almost perfect game.
"There were some things tonight where you could see he was not full of confidence. I think a goalkeeper once in a while has a right not to have a big performance.
"But he will stay a very good goalkeeper, every person sometimes has this small period of not being on top form.
"If a player is playing a lesser game now and then, it is not always the reason to make a substitution."
