Stoke City representatives travelled to Hannover on Wednesday for further negotiations over striker Mame Diouf.
Stoke, who missed out on the signing of Benfica attacker Nelson Oliveira in late July, have revived their interest in Senegal international Diouf.
Potters chairman Peter Coates has been reluctant to sanction a heavy investment in the 25-old-year, a former Manchester United reserve, as the Bundesliga club seek €8 million despite the player being in the final year of his contract.
On Wednesday, though, Stoke directors Tony Scholes and Mark Cartwright travelled to Germany to meet with Diouf's agent, Jim Solbakken, and Hannover general manager Dirk Dufner.
"They wanted to meet us for a one-to-one conversation," Dufner told Bild. "That's what we did. But we have not reached an agreement."
Bild believes Stoke have doubled their previous €3 million offer but Scholes and Cartwright have returned to England and Dufner said: "They will now put their heads together.
"We will see if they come up with a new offer or not. If Stoke meet the price we suggested, we will consider it."
It is suggested that Hannover will consider selling Diouf for around €7 million.
