The 21-year-old is in high demand this January after an excellent start to the season, but it was thought that Turkish giants Galatasaray were the favourites for Tannane's signature after talks with the players agent.
However, Atalanta, who have had a bid for Heerenveen winger Sam Larsson turned down, have now thrown their hat into the ring and TC Tubantia are reporting that they have officially opened talks with Heracles.
Heracles will now hope the Serie A side's interest will start a bidding war with Galatasaray for the Netherlands U21 international, who's contract runs out in the summer. It is believed that Heracles are hoping to earn €3 million from the sale of their star player.
