Borussia Dortmund midfielder Axel Witsel believes that Jadon Sancho can be one of the best in the world.

Sancho, who is being linked with Manchester United, has impressed in his second season in Germany, topping the Bundesliga assist charts for Dortmund.

And Witsel believes there is so much more to come from the 19-year-old who left Manchester City last summer.

"It's good because he's getting a chance here in Germany," Witsel said about Sancho in an interview with Copa 90.

"English players used to stay in England but what Jadon is doing now is amazing.

"He has a lot of quality, I think he can be one of the top wingers in the world if he keeps working hard and listens to us a little bit!"
