Stoke have reached an agreement with Monaco for the season-long loan of Eidur Gudjohnsen.
The former Chelsea and Barcelona striker, who spent last season on loan at Tottenham, is currently having discussions at the Britannia Stadium.
If the 31-year-old were to sign he would be the second deadline day capture for the Potters with possibly more to come.
Former midfielder Salif Diao, whose contract expired at the end of last season, has re-joined the club on a two-year deal while Stoke are also in discussions with Portsmouth's Marc Wilson.
In addition to his new contract the 33-year-old Senegalese will also take on an ambassadorial role for the club in Africa and other parts of the world.
"It's great to be back home. I love the club and I love the supporters, so I always hoped something could be sorted out," he said.
"I feel there is still unfinished business and I want to help Stoke City continue the excellent progress made in my time here.
"Tony Pulis is more than a manager to me and I want to repay the faith that he has shown in my ability at this stage in my career.
"I believe I can still make a big contribution as a player but it is also very exciting that I have another important role to play which could help bring new talent to the club in the future."
Pulis added: "It is fantastic to see Salif back because he is not only an experienced head, he is a good person to have around the place.
