The Potters are in initial talks to sign former Manchester United striker Diouf from Hannover , says the Daily Star.
"They [Stoke] wanted to come over and have a personal chat. This is what we have done, they were welcome," said Hannover general manager Dirk Dufner.
"We have not reached an agreement.
"As far as I am concerned, Stoke feel we will automatically agree to a transfer at some point, as the contract expiry date is just 12 months off.
"But we do not plan to do so. I feel they will now consult, and then we will see whether we receive a written offer or not.
"We would think about that if Stoke agree to what we have told them."
