Thing is Mata is popular amongst the hard-core United fans, so yeah getting rid will puss them off a bit, but getting shut after signing the world's most expensive player and maybe for ing matas hand to ask to leave, will hardly cause a ripple amongst United fans, think he's been gone since day 1, just mourinho wants to time it right for zero blowback over it.
Exactly mate it's what suits Jose he's not bothered about players or egos or fans as such. Win win win no matter in every aspect ( which is why he's good ) oh and spend lol
