Celtic are the latest club to join the race to sign want-away Arsenal goalkeeper Lukasz Fabianski this summer.
The Daily Mail reports how the Poland international has rejected the offer of a new three-year contract to remain in north London, and looks set to leave on a free transfer at the end of the season.
Gunners boss Arsene Wenger is keen to keep Fabianski at the Emirates Stadium, having been impressed by his performances when standing in for Wojciech Szczesny in 2013/14.
However, the 28-year-old is eager for more regular first-team football, and is ready to quit Arsenal in order to realise that ambition.
Neil Lennon's alleged interest in bringing Fabianski to Celtic Park raises further doubts about the long-term future of Fraser Forster.
Celtic will face competition for the player's signature from the likes of FC Basle, Schalke, Sevilla and Leicester City, but hope that the offer of Champions League football will be enough to lure Fabianski north of the border.
