He said: “We deserve credit because we have had so many problems this season.
“It’s always difficult when you chase all competitions and get knocked out, I can’t even say how many emotions I have, it has been an incredible season for me.
“It was a very tactical game and I think there was fatigue but we had great motivation.”
Cech added: “I’ve heard a lot about the FA Cup and this feeling is amazing. We have been chasing all four trophies. We lost a semi-final (Champions League) on penalties and we lost the Premiership at the last moment so this Cup is a real achievement.”
