Celtic have made their first formal offer for Sampdoria defender Omar Colley, claim reports, worth a total €8.5m.
According to Il Secolo XIX newspaper, the Scottish title holders proposed €2m for the loan, plus an obligation to buy at the end of the season for a further €6.5m.
Negotiations are set to continue, because Samp are asking for closer to €10-11m in total for the Gambia international.
The 27-year-old centre-back has also been linked with West Ham United.
Samp paid €8m plus bonuses to get Colley from KRC Genk in 2018, so want to make a profit on his sale.
