Celtic are reportedly set to make another bid for Norway striker Erik Huseklepp after losing out on his signature to Bari in January.
The 26-year-old, who has 19 caps for his country, chose to join the Italian club from SK Brann for an undisclosed fee at the beginning of the year.
However, Bari were relegated to Serie B and there are concerns that they have not paid the full fee for the forward to his former Norwegian club.
Huseklepp's agent Luca Pensi said: "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.
"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. Between an interest and a real negotiation, there is a big difference."
