The 21-year-old attacker is almost certain to leave Heracles this January with his contract with the club up in the summer.
Galatasaray are reportedly close to agreeing a fee for Tannane, and the players agent, Guido Albers, has admitted they will discuss their proposal later this week. However if the Turkish club fail to convince Tannane then the winger also has interest from Italy and Spain.
Albers told VI, "Galatasaray is a great club and Turkey is a country where Osama would fit,"
"We have a proposal from Galatasaray and want to hear this week whether it makes sense to talk further. If not, then there is enough interest from other clubs."
Tannane has been in outstanding form so far this season, scoring seven goals in eleven Eredivisie ties.
