normally they are refering to calling Kaka a bottler for pulling out of the City move when the AC fans weren't far off rioting.
ITs nuts, I don't like Cook at all, he comes across as a pratt, but the e-mail he sent to his mate was nothing more than a little banter between friends, its not offensive, Onouha's mother is playing it up to get a bigger contract offered, and its all a bit sickening. Guy mocks an e-mail he receives, according to her it was worse than hearing she had cancer, she kept it quiet to not upset her family..... then went to The Sun to tell them all about it.
He was an idiot, he made a fairly stupid error in sending it to the wrong person, the mail wasn't malicious, didn't say he was happy she had cancer, you shouldn't get fired/resign over stuff like that, but media like blowing anything out of proportion.
The Sun's little crusade of his previous incidents, because calling Kaka a bottler is somehow truly terrible and makes him a bad person......... state of the world we're in though, silly mistake that means nothing will cost you a job if people WANT to make a big deal out of nothing.
