Louis van Gaal will sit down with his players after their tour and tell them whether they have a future at Manchester United.
Van Gaal and his 25-man squad fly back to Manchester in the early hours of Tuesday morning after their final game of the US tour against Liverpool.
Van Gaal said:
Manchester United have racked up wins over the Los Angeles Galaxy, Roma, Inter Milan and Real Madrid, but the manager is still unhappy with certain aspects of his squad.
Javier Hernandez, Shinji Kagawa and Wilfried Zaha face uncertain futures after limited playing time in America while Marouane Fellaini and Anderson, who have not made the trip, could also be shown the door.
Van Gaal has sent coach Marcel Bout back to England to work with the likes of Robin van Persie, Adnan Januzaj, and Fellaini, who have been given time off following their exploits at the World Cup.
