The playmaker says people close to him were worried when the Portuguese coach followed him to the Theatre of Dreams
Juan Mata has admitted family and friends were concerned about Jose Mourinho's arrival at Manchester United but the Spaniard didn't have the same worries about his former coach.
Mourinho, who sold the playmaker to the Red Devils after only working with him for six months, replaced Louis Van Gaal at Old Trafford six days after Mata scored a goal in Man Utd's FA Cup final win in 2016.
Speculation persisted that Mourinho would once again jettison Mata, but the player himself was intent on to prove himself despite his family and friends expressing concern about the Portuguese manager.
