The Daily Paper states that the Portuguese tactician will give every play, including Mata a chance to prove themselves during pre-season training.
Mata’s place at Man Utd has been called into question following Jose Mourinho’s appointment in place of Louis van Gaal.
Mourinho offloaded Mata from Chelsea to United during his second spell with the Blues. The Spanish newspaper El Confidencial have claimed the Portuguese manager is open to selling Spain Mata over the summer transfer window.
Mata scored 10 times while providing 11 assists for United last season and has another two-years left on his contract.
