Luis Suarez
Ah, calm yourselves down. Sure, it would've been lovely if Luis Suarez had done what
Miroslav Klose did earlier this season and owned up to it being a handball, but the reason you've heard about Klose's action is because it's so rare. It's not particularly fair or realistic to criticise Suarez for not doing the extraordinary and unusual. In any case, it isn't absolutely sure that the handball was deliberate - Suarez jerked his arm back as the ball struck it, suggesting that he was actually trying to get the offending limb out of the way, rather than move towards the ball. Given the small amount of reaction time between his original shot rebounding towards him, one cannot say for certain that this was a deliberate act, and therefore cannot say for certain that (in this case) Suarez is a cheat. Anyway, do you really not already have enough reasons to dislike him?
