Defeat at Arsenal was all my fault, says Chelsea keeper Cech

• More Premier League news

The Czech goalkeeper failed to claim a corner, allowing former Chelsea star William Gallas to head in the only goal at Emirates Stadium yesterday.

The incident has left Cech with a bitter memory and he has vowed to study the video of the mistake to prevent a repeat.

He said: "You have to analyse yourself and see why you made a mistake, what was the moment you could have done better.

"Of course you have to watch it, but in the end you have to turn the page and go on. I am disappointed because the game was decided by my mistake.

"There is no explanation or excuse. It was a simple as that. In the first half, they had no chances. They had nothing, only a bit of possession but that was it. We controlled every movement they tried to do. They had one corner, I made a mistake and they were 1-0 up.

"This is part of the game. You play in these big games with this passion. These are the best games to play in and you always want to do your best. I love this type of game, but will not remember this one as one of the best ones."

Former Chelsea star Gallas admitted he was shocked at Cech's error having played in front of him so often.

The Arsenal skipper said: "Everybody knows Petr. For me he is one of the best goalkeepers in the world.

"I was surprised to see the ball coming at my head. I saw him and I thought he would catch the ball but he missed the ball because [the flight of] the ball was a little bit strange. I was lucky."

The man Gallas replaced at Emirates Stadium, Ashley Cole, had a miserable afternoon against his former club and could be facing an Football Association misconduct charge after apparently flicking a V-sign at Arsenal fans.

The defender played at Arsenal for the first time since moving and was barracked throughout.
