Arsene Wenger has challenged his young Arsenal squad not to make the same mistakes as they did in a crushing defeat to Manchester United by failing to "turn up" at Stamford Bridge on Sunday.
Arsenal could blow the title race wide open with victory over Chelsea, which would move them within three points of Carlo Ancelotti's side. However, by the same token, suffer another loss and the Gunners' championship ambitions will look to be all but over once again.
Wenger's team came up short in every department against United last weekend, when the champions romped to a 3-1 win at Emirates Stadium. The French coach, however, believes lessons have been taken on board.
"The biggest regret I have from against Manchester United is that we gave them too much freedom and allowed them to play too much in a game where we should have been dictating," Wenger said.
"My team wanted it so much that sometimes you can be a little bit restricted and our target is to get that freedom to play against Chelsea.
"I am convinced that we are capable to win everywhere in the world, but of course we need to turn up with a good performance."
