Polish keeper Grzegorz Sandomierski will not be in goal for Celtic in their Europa League qualifiers – even if the Parkhead club sign him before Monday's deadline.
The 21-year-old – who Neil Lennon confirmed in yesterday's SportTimes is a man they are interested in – has already played in the tournament this season.
In the first round, his team, Jagiellonia Bialystok, crashed out 2-1 on aggregate to Irtysho from Kazakhstan.
Under Uefa rules, anyone who has played in the qualifying rounds will be eligible to play for another club from the Group Stage onwards, provided the team they have already appeared for is not in the competition.
So if Sandomierski does sign for Celtic, he would have to sit out the final knock-out round on August 18 and 25, and hope his new club can get through to the Group Stage when he could make his European debut for the Hoops.
This would mean either Lukasz Zaluska or Dominic Cervi playing in goal for the qualifying ties. For Lennon, it is another complication in what has already been a frustrating search for a new keeper.
The latest news from Poland is that it could take as much as £2.7million to persuade Bialystok to sell Sandiomerski.
That's the price Belgian club Genk have been quoted as they compete with Celtic for the youngster who has already forced his way into Poland's national team.
Sources in Poland also claim the Parkhead club have already had one offer rejected. Told by cash-strapped Bialystok how much they want for Sandomierski, Celtic are reported not to have baulked but to have said they will go away and consider it.
But Sandomierski is not the only option Lennon is considering. An enquiry to Reading over the availability on loan of England Under-21 keeper Alex McCarthy could see the highly-rated shot-stopper heading north.
Lennon was also impressed by free agent Gerhard Tremmell when he played against Celtic for Swansea in midweek.
And a return to Parkhead for Fraser Forster has not been ruled out, though Newcastle are holding out for at least £2m.
Meanwhile, Celtic skipper Scott Brown is set to seal a new deal. Brown, signed by Gordon Strachan in 2007 on a four-year deal, is not in the final season of that contract.
However, negotiations have been fruitful and the midfielder is expected to commit to a longer deal.
