Petr Cech insists his confidence will remain undamaged by Chelsea's recent defensive calamities.
The Blues have conceded seven times in two matches with Cech looking uncomfortable throughout the 4-4 Champions League draw with Liverpool.
Boss Guus Hiddink must decide whether to drop his usually unflappable keeper for Saturday's FA Cup semi-final against Arsenal at Wembley.
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.''
Stamford Bridge watched in amazement as Chelsea secured passage into the Champions League last four with a 7-5 aggregate victory.
The club are challenging for silverware on two fronts - the Barclays Premier League appears beyond their grasp - and Cech has been impressed by Hiddink's contribution.
Hiddink is due to leave the club at the end of the season but Cech would like to see him appointed on a permanent basis.
"The team is very happy with the manager - you can see that on the pitch'' he said. "I have to say I want him to stay because when you have a manager who brings success you always say yes.''
