They claim that Spanish side Las Palmas, Italian outfits Fiorentina and Sampdoria as well as Turkish giants Galatasaray and Brazilian club Gremio are all keen on the player.

West Ham fought hard in the summer to sign a big-name striker but in the end made moves to sign both Calleri and Simone Zaza on loan. Both flopped, with the Italian also set to leave the club this month.
