Cech told the Mirror: "I still feel I'm improving every season and hopefully next year will be another step.
"It was fair for people to criticise but some of them criticised me for the whole season which was not true.
"I had been playing well, training well and keeping clean sheets.
"We had the best defence in the Premier League.
"What happened at Reading even made me stronger because when you go through a difficult period you know it's not always like that.
"I never have any fear on the pitch so I don't feel it's affected me."
