Manchester United will wear its away kit in the FA Cup final against Crystal Palace on May 21, it has been confirmed.
A coin toss was made, due to the club's kits clashing, and the Red Devils lost, meaning they will wear white, in a repeat of the 1990 final between the two clubs.
United drew with Palace 3-3 on that occasion at Wembley, with United going on to win the replay 1-0.
