Yeah, yellows can't be given retrospectively otherwise there would no doubt be loads more to review each week. Whole incident was a farce but in answer to your question on Torres I'm pretty sure it's because his balls fell off a few years ago..
No, not a red card, so i suppose there's not much they can do. That's the rule isn't it?
Meh, wasn't a red card offence so no big shock. Stupid and childish of him though.
The most annoying thing about it was Torres' pathetic reaction, why the hell did he not even square up to him?!?
