Sunderland sporting director Kristjaan Speakman has no doubts about the potential of Manchester United midfielder Amad Diallo.

Amad has just completed an outstanding loan with the Black Cats.

Speaking told Sunderland's Youtube channel, Speakman stated: "Amad's performances in the games - not just with the ball but some of his defensive work, his energy, his pressing - the way he has taken to the supporters, he's absolutely bought in to what we required of him. And he's got a really nice personality which I think hundreds and thousands of Sunderland supporters have taken to.

"We're really proud that we have managed to help his career, too. He came here off the back of the loan move to Glasgow [Rangers] and he himself would say he probably arrived with lower confidence that he is used to, so to be able to build that player back up hopefully bodes well for him, but it also bodes well for us when we are trying to recruit either on loan or with permanent transfers that this is a really good place to come for players, regardless of age."
