As announced last month, Anthony Martial is leaving the club after making 317 appearances. The striker scored 90 goals and won the Europa League, the FA Cup and two Carabao Cups during his nine years at United.
Fellow Frenchman Raphael Varane is also departing following three seasons at Old Trafford. The defender brought a great deal of class and experience to the team throughout his 95 appearances.
