Surely it should be slander rather than libel as it was spoken rather than written, unless there is some spurious arguement about it being published as it was broadcast rather than simply said in front of witnesses.
In either case I thought there was a defence of fair comment in such cases which, based on the evidence available at the time, was surely what it was ( it was a damn sight more restrained than what I was shouting at the TV ).
The second reason that I think that this case will never come to court is that the plaintiff (Tevez) has to prove damage to his reputation, a reputation that is already fucked beyond all redemption due to his actions and the actions of his slimeball advisor. Even if he did win his award would be about 2p and it is far more likely that the judge would throw out the case as a frivolous prosecution and award costs to the defence.
