Neil Lennon is confident Celtic are making progress in their attempt to sign Polish goalkeeper Grzegorz Sandomierski.
The 21-year-old, who has also attracted interest from Everton, has been targeted by the Glasgow giants as they search for a stopper to compete with current custodian Lukasz Zaluska.
On Friday, the Polish club's chief executive Cezary Kulesza said an offer of a trial wouldn't be granted until the two clubs could agree a fee.
But speaking after Celtic's 1-0 win over Aberdeen at Pittodrie, Lennon said: "I'm not sure if it's a done deal, I haven't spoken to Peter today, but we might be further down the line with that one.
"He's a goalkeeper we do like and we feel he has huge potential."
The claim comes after the player's agent told BBC Scotland's Sportsound programme that the Polish club had rejected Celtic's offer and that Belgian side Genk were in the driving seat to sign the player.
