Greek club Panathinaikos are reportedly interested in Celtic's Reo Hatate.
The midfielder has not played this season and was mostly sidelined last campaign under Martin O'Neill.
Hatate, 28, is keen to leave for more first-team opportunities.
The Daily Record claims Panathinaikos are aware of his situation and could offer him a move.
Despite being out of favour, Hatate is still valued highly and would command a significant seven-figure transfer fee due to having two years left on his contract.

Panathinaikos, who had a poor season last year, are looking to revamp their squad under the leadership of Jacob Neestrup.
They could reportedly offer Hatate a pay rise compared to his current wages at Celtic.
There is reported interest in Hatate from other European clubs and teams in the Middle East as well.
Meanwhile, Celtic are poised to sell another midfielder, Arne Engels, to West Ham United for around £25 million.
They have already brought in German player Mika Baur from Paderborn and are eyeing Hajduk Split’s Niko Sigur, Torino's Gvidas Gineitis, and Hibs' Miguel Chaiwa to bolster their squad.
