Hannover have confirmed Mame Biram Diouf is in talks with Stoke City.

Sporting director Dirk Dufner concedes that Diouf's representative has opened talks with Stoke, but insists there is no guarantee that a deal will be done.

He told Bild: "I see the opportunities still not bad.

"At the moment, Mame will not sign.

"It is not bad if he waits for the end of the transfer period, then signs just after 31st August."
