It certainly wasn't a good challenge, and you could perhaps cite him for being optimistic, but I see no malintent there, Eduardo is a victim of his own deft skill, a lot of players would not have tried to flick the ball away like that. I think he did see the challenge coming, judging by the poor quality of the pass. The challenge was definitely a red card offence, he missed the ball and took the player out. It might even warrant an extended suspension due to the seriousness of the injury sustained, but it wasn't malicious. Roy Keane/Stuart Pearce et al used to get away with worse than that on a weekly basis.
