Hoffenheim striker Demba Ba is undergoing a medical at Stoke ahead of a proposed move to the Britannia Stadium.
Stoke submitted a £5.9million bid for Ba on Thursday and the German club have now given the striker permission to hold talks with the Potters.
Ba future at Hoffenheim has been in doubt since he refused to travel with the club to their winter training camp in Spain amid interest from West Ham United.
He was threatened with legal action by the club’s general manager, although Ba suggested in a statement on his own website that Hoffenheim had gone back on a promise to let him move to England.
“I regret the situation and I suffer from it,” Ba said on 6 January. “The club gave me a green light to leave under certain conditions which have been met. I hope that the promises will be fulfilled.”
Stoke boss Tony Pulis is keen to bolster his attacking options and sees Ba as a key addition to his squad with the likes of Tuncay and Eidur Gudjohnsen linked with moves away from the club.
The 25-year-old has scored six goals in the Bundesliga so far this season.
