Arsenal goalkeeper Petr Cech says self-belief has been a foundation for his career success.

Cech meets his former Chelsea teammates today in the Community Shield.

“I think you can't have doubts," he told the Arsenal Magazine. “I believe in what I can do.

“I believe in my skills, I believe in my team-mates and that together we can achieve the targets and goals we set up. That means winning a football game.

“You cannot have a fear of making a mistake because a football game can finish only three ways - you win, you lose or you draw. You have to accept that.

“Maybe you win and maybe you lose. But if you give 100 per cent, you have the biggest chance that you can win.

“This is probably the reason that I managed to keep my continuity for such a long time.

“I'm a winner in a way that I go to the pitch and I know that if I do my job 100 per cent, I have a chance to win the game.

“I never have a doubt that I can't do that."
