During the press conference Wenger was asked what he thought of the transfer and could have stopped at saying Mata is a fantastic player and he's surpised he's being sold. But Wenger decides to take another step and starts talking about 'respecting fairness' because Chelsea could have sold him last week before they had played Man Utd. Suggesting Chelsea have some sort of advantage and done something underhanded. Nobody asked him if he thought it was fair or if Chelsea had done something cynical.
