Look, do I blame Suarez for cheating? No. He knows the rules and he's probably been taught to stop a sure goal any way he can.
I think it was just a reflex actually and not something he was taught.
Anyway, what the problem here is, is the rules, it would be more fair if the attacking team just got awarded the goal instead of having to rely on a penalty shot here. But should the rules be changed so fundamentally because of a situation that happens so rarely? I would say "no".
