Borussia Dortmund chief Michael Zorc concedes Jadon Sancho is struggling for form.

The England international winger, a summer target for Manchester United, is yet to score in the Bundesliga this season.

Zorc told a press conference this week: "I believe it is easy to see that he is not in the best of form. I can tell he tries hard when he's subbed onto the pitch. He tries to force the lightness and fluidity that he has onto himself.

"Jadon is a player who doesn't talk a lot but who delivers answers on the pitch.

"Whether this is tomorrow, in a week or at some other point, I don't know. What I do know is that it will happen."
