Its because its Jose people believe he will pull this off and he is doing this for the better of the TEAM not the individual.
He cannot change Mata's fundamental style. If Mata's lateral style doesn't work for the side he should have been sold, not turned into a cart horse.
And I'll ask again if Rafa had done this with Mata, would you have been happy? Absolutely not, and that's why im calling bullshit on this total acceptance of it.
