Arsenal boss Arsene Wenger took another swipe at Birmingham City midfielder Craig Gardner yesterday over his tackle on Cesc Fabregas.

With memories of the Ryan Shawcross tackle which broke Aaron Ramsey's leg still fresh in his mind, Wenger is still unhappy about the challenge on Fabregas by Gardner on Saturday, and the fact that pundits like Alan Hansen insist aggression is the key to beating Arsenal.

"You should analyse the tackle again and you will not be surprised that he is injured," said Wenger.

"It's the left foot which injured Cesc. I don't know why the guy needs to tackle with his left foot. When you look at how Ramsey broke his leg, it's the left foot of Shawcross that broke his leg. Once a big player goes in and has full weight on the ball when two face each other, the other foot comes in when you have full power and your ligaments or your bones go. The lucky thing for Cesc was that he told me he saw it coming and didn't go for the ball.

"If you analyse the tackle and you show me in slow motion that it's a regular tackle and show me why, then I am ready to accept it. But it wasn't. There is a difference between commitment and aggression. I like commitment, I have nothing against teams playing against us with commitment."
