Mats Hummels is full of praise for Borussia Dortmund teammate Jadon Sancho.

BVB fought off major interest from Manchester United over the summer to keep hold of the England international.

Hummels said, "He has such timing in his passing game and he is very calm in front of goal.

"He contributes so much with his assists.

"He can be one of the best players in the world and it's up to him because he doesn't lack the many qualities required for that."
