United may have been unable to match the blistering pace set at the Premier League summit by Manchester City, or go as far as hoped in the Champions League, but the Portuguese will count another trophy as a successful season and a platform from which to kick on next season.
Mourinho named his team against Watford on the final day of the league season with one eye very much on the cup clash at Wembley, making seven changes with Sergio Romero, Daley Blind, Matteo Darmian, Marcos Rojo and Eric Bailly all handed rare starts.
However, with the FA Cup on the line, Mourinho will revert back to his first-choice eleven, with Paul Pogba, Antonio Valencia, Nemanja Matić, Jesse Lingard and David De Gea among those set to return to the line-up.
The United boss is, however, sweating over the fitness of two players, with Romelu Lukaku and Anthony Martial both in a race to be fit in time for the club's final game of the season.
Lukaku is still recovering from the ankle injury he picked up in the victory over Arsenal three weeks ago while Martial was left out of the squad for the Watford game after hurting his knee in training.
