Sunderland midfielder Sebastian Larsson is backing Victor Lindelof for success with Manchester United.
The Sweden centre-half, 21, will seal a £35million move from Benfica in the next few days.
Lindelof will fly to Manchester for a medical on Wednesday. And Larsson told The Sun: “You cannot deny his qualities.
“He has burst on to the scene and done superbly at club and international level. I've been so impressed by him whenever I've played with him.
“He's an important player for us in the Sweden team now and that shows maturity.
“But not only does he have the quality on the pitch but he has a calm and sensible head on him as well.
“He is a humble guy and has a good future ahead of him."
He added: “The major thing is his quality is undoubted and he has his feet on the ground."
