Borussia Dortmund manager Edin Terzic knows how good Jadon Sancho can be at his very best.

The attacking midfielder has not shown his best level at Manchester United in two seasons.

While Sancho is likely to be given one more season to prove his worth, a move away this summer is not impossible either.

Asked about Sancho after a friendly win over United, Dortmund boss Terzic stated: “Jadon has been doing magic with us long enough to know his quality.

“He's a fantastic lad but he's signed to Man Utd now and we don't comment on players who are signed to other clubs.

"We were happy to see him, he was happy to see us and we wish him all the best for the coming season at Man United."
