Celtic are in the frame for Bari midfielder Erik Huseklepp.
The Norway international is also interesting Stoke City as he considers his options following Bari's relegation.
"This morning I met with Bari sporting director Guido Angelozzi in Milan, and with it we are trying to find a solution that satisfies both the player and Bari, who have said they are keen to sell," explained agent Luca Pensi.
"Regarding the news of Celtic, it is reliable. They have reported to us their interest in the player.
"Of course then you have to find an agreement that satisfies all parties, with the Scottish club in this case still having to make a concrete offer to Bari.
"For now, I want to reiterate, however, that there is still nothing concrete. There is a big difference between an interest and a real negotiation."
