Sunderland manager Tony Mowbray admits he would like to keep working with Manchester United after Amad Diallo's outstanding loan spell this season.
Amad joined the Black Cats for the season last summer, with Mowbray hoping to add star quality for his sides' return to the Championship.
The 20-year-old enjoyed and outstanding campaign at the Stadium of Light, his 14 goals and three assists helping his side into the play-offs, where they were beaten by the eventually promoted Luton Town in the semi-finals.
