Since suffering a fractured skull in 2007, following a challenge from Stephen Hunt, questions have been asked of the Czech international and whether he has managed to return to his best form.
But the Blues' stopper has been pleased with his displays for the Stamford Bridge club this season.He told the Evening Standard: "I've been really happy with what I've done so far this season. I think I've played well and am enjoying it.
"These moments are good going forward because when you come through a difficult period it makes you stronger. I have stayed injury free the whole year, which was my aim. When you are injury free and able to play with no limits, it's a big help.
"If you are struggling as a team a little bit, you need to play well in defence because it is the first area you can cope with," Cech added. "If you defend well, no matter how bad you play it will always bring you something.
"If things aren't going well, getting back to basics, defending well, is the key and we have had a pretty good run in the League."
