Lazio have set a transfer valuation of £13m for reported Celtic target Matteo Cancellieri.
Reports in Italy claim the Parkhead club are interested in the winger, and his team-mate Gustav Isaksen.
However, TuttoMercatoWeb report that the transfer fee Lazio want to receive for Cancellieri could prove to be a stumbling block for interested clubs.
Lazio are keen to sell players not central to Gennaro Gattuso's plans at the club.
The Italian side want to bring in a defender and a striker, and so need to move on players who do not have a future at the club.
Cancellieri is one of the players expected to leave the club this summer with his game time to be limited at Lazio if he were to remain at the club.
The winger is contracted until 2026 and has also been linked with Torino, Fiorentina and Olympiacos.
Lazio are thought to be awaiting offers for the player as they hope to bring in a significant fee for Cancellieri.
Isaksen, who had also been linked with Celtic last summer, is currently sidelined after suffering an injury last season.
But the player's time out of action is not thought to impact Lazio's desire to move on Cancellieri this summer.
Celtic are set to break their transfer record to sign Bodo/Glimt forward Kasper Hogh in a deal worth £11m-plus.
The Danish internaitonalist is expected to sign a long-term contract with the club.
