Think the closest thing in recent years might have been Gallas stomping some Bolton player. It might have been Mark Davies. I'm a bit vague on the details but I know he missed a month or two because of a hairline fracture and a damaged ankle ligamanent. I know some people on AM were cheering because Bolton had a history of injuring our players.
Diaby fractured Wesley Sneijder's leg in preseason too back when we played Real Madrid. He also broke Ivan Campo's foot back in 2006. He's been dishing out plenty of horror tackles throughout the years to be honest. He's always been a brainless player.
