The agent of Barcelona attacker Cristian Tello admits his future could be with Olympique Marseille.
The winger is playing this season on-loan with Fiorentina.
Josep Maria Orobitg told Foot Mercato: "Tello is a player on loan from Barca to Fiorentina. Fiorentina has a very affordable option. Tello is a very special player. He's explosive.
"What will Fio do? If it does not take the option, the player is under contract with Barça.
"(Andoni) Zubizarreta was the man who recruited him to Barça. He knows him very well. But we did not talk about it. If it is a good season and Fiorentina wants to recruit him definitively, Barça can block the operation thanks to a clause that it can raise (against payment of a sum of money) and to keep him or resell him for a higher price.
"But I think this scenario is unlikely to happen. But Barca hold the cards."
