Arsenal goalkeeper Petr Cech recognises his form can be better this season.

Cech says he was "lucky" and "got away" with several errors in Arsenal's win over Cardiff, but feels his overall game has been strong.

"Everyone picked up on two passes against Manchester City and Cardiff," Cech told Sky Sports. "Obviously, from that number of passes you can make a mistake. I try not to make a mistake. That's clear and obvious.

"You want to use the goalkeeper as an advantage as a spare man. I am not happy with these two passes. We got away with it at Cardiff but I think my overall game has been strong.

"If the team wins and from your mistake nothing happens it's a good way to realise you have to be more precise next time.

"I'm lucky nothing bad happened. I know that everyone will be waiting for the next mistake and trying to put more pressure but that's the way it goes. Playing in goal in the Premier League you play with lots of pressure."
