Dortmund imposed an artificial deadline of Monday for a conclusion of talks with Manchester United, who want to buy the England winger. The deadline passed with no deal and Dortmund said the 20-year-old would now be staying, although media reports say United will keep trying.

“This is a great chance for us to become even better, to make another step forward. And that must be our goal for this season. I have the feeling that we can do much more,” Hummels said at Dortmund’s pre-season training camp in Switzerland.

“He can be the player who makes the difference. He has unlimited potential. If he wants to show that for another year or more with us, I’m very happy about that.”

Reports have said Dortmund, runners-up last term to Bayern Munich in the Bundesliga, want 120 million euros (141 million dollars) for Sancho.

“We plan with Jadon. He will play with us next season. The decision is final,” sporting director Michael Zorc said in a statement late on Monday.

The new season starts in September.
