I mean from Mourinho's point of view. If you had a great player in the squad but not playing to your expectation, you would have rather him staying than him leaving the squad. Isn't it? The decision now lies with Mata. As a top-class player, would you rather sit on the bench or play only 60mins? No way! But Mourinho played it very well in the media, making it looked as if Mata was the one who wants to leave, and deflecting the blame to Mata.
