The issue with Mata was simple, he didn't fit Jose's plans whether people like it or not, he was a huge cash kitty sat on the bench that the club chose to take advantage of. People also forget that Jose and Mata spoke about what was best for both parties and he was allowed to leave. Now lets not get this mis-translated with he was shit, he wasn't, but a player that can fetch the sort of money he could doesn't deserve to be benched, good or not. Some of this cash was used to buy Matic and if people argue against that then I am sorry but that was a fucking quality buy. You can argue all day about what he may, or may not of done, we will never know because Jose didn't think he was fitting of the role and thus was sold. This is also a WC year were he must be playing to have any chance, it wasn't happening here so the decision was right IMO from both parties.
