The midfielder was certainly able to offer his views on former manager Jose Mourinho before the game, but he could not offer anything at all on the field.
Handed a temporary reprieve from the bench following the three match ban for Wayne Rooney, Mata has failed to show his manager much to convince him that he, and not Rooney should be playing in that number ten role.
In fact, all he probably did was convince Jose Mourinho he made the right decision when allowing the Spaniard to leave.
