Can't disagree with any of that, really. There needs to be harsh retrospective punishments handed out if we really want to stamp it out the game. But you'd need to give folk the benefit of the doubt. In this case I think it would be harsh to hammer Bale because he was going at pace and clipped. It's tough. And we don't have governing bodies strong enough to make tough/unpopular decisions.
Credit to Suarez last night. Fouled by Cuelar out on the right hand side but managed to stay on his feet. Although he still had a long way to go and a lot to do he kept going and the ref played advantage. 99 out of 100 players would have went down or stopped and taken the free kick.
