Can we really have a player who cost us £38 m, will be on £150 k + p/w, is used to been a starter, and has already been deemed not up the Mourinho system as a squad player? Because that's what he'll have to be if he stays
Added to that if we do keep on spending as we are then we are going to need to get some money back, and in Mata we have someone who might actually fetch a good fee, also worth remembering that next year he'll only have one year left on his contract, which would likely mean selling him for alot less than he's worth now.
I'm not knocking him, and I like him, but he is not a winger, and has never really been trusted in the number 10 position, so for me it's time for him to go.
