Borussia Dortmund sporting director Michael Zorc has strongly denied talk of an agreement with Manchester United for midfielder Ilkay Gundogan, insisting he has not spoken to the Premier League side since November.

Reports in the German press last Friday claimed United had agreed a fee of £21.5m to sign the Germany international this summer.

But Zorc insists the Bundesliga side have not been contacted about the 24-year-old midfielder.

The Dortmund sporting director did however admit to talks with United about another matter, but would not disclose the details over who or what the conversation was about.

"There is no signature, no contract, no offer, no demand, there is not even any contact," Zorc said in response to claims suggesting Gundogan moving to United is a done deal.

"The last time I spoke with Manchester United was in November 2014 and it was about something else."

Dortmund captains Mats Hummels also remains strongly linked with a move to Old Trafford. In recent weeks the Germany international has indicated he will consider his future at the end of the season with his manager Jurgen Klopp admitting there is a chance the centre half will leave.

"He's good enough for Manchester United. He's told me he's thinking things over," Klopp told DW Sport.

"We're always looking around the market ourselves. That we want to keep Mats is beyond question. How that works out I don't know. There's always a list of players who would be interesting in the event that you need them."

But with Klopp leaving Dortmund at the end of the season, most recent reports suggest United must wait to consult his successor Thomas Tuchel in the summer before any deal can be struck.

As well as the German duo of Gundogan and Hummels, United are also reportedly in talks with PSV Eindhoven starlet Memphis Depay. However, the Netherlands international has refused to be drawn on such speculation.
