The pair are shining for United's U21 team.
"Nick's got talent," he told ManUtd.com. "He can play anywhere on a football pitch as he's got really good ability.
"Adnan is still developing but there's no doubt he's got talent too. He's got a good footballing brain and a good touch. We're trying to get him stronger and fitter and he's getting to know the Manchester United style of play as well.
"He's grown up a certain way and I think he has had a tremendous education over in Belgium. He's come over here with good technique and is desperate to be a footballer as well so he's got a lot of things going for him."
