Petr Cech insists conceding seven times in two home games will not affect his confidence. But while Cech admits he was twice at fault for the recent flurry of goals, he insists the errors should not overshadow his general form.
"I felt I was playing really well until the Bolton game on the weekend," said the Czech international.
"It was a difficult game but there was a goal I didn't like against Bolton and another one against Liverpool.
"But I've had many good games when everything went right so I won't let what has happened affect my confidence."
Fabio Aurelio exposed Cech during a 35-yard free-kick at Stamford Bridge and the 26-year-old refused to excuse his blunder.
"It was a strange game for myself against Liverpool. I did all the preparation right and tried my best but it just didn't happen," he said.
"Everyone is excited by games like that but not me because I conceded four goals and made a mistake for the first one.
"It's not a good way for a keeper. Of course I hold my hand up for the first. I was caught too easily.
"I slipped a little bit but that's not an excuse - it's a goal I shouldn't have conceded."
