Celtic must move quickly if they're to land Dundee United goalkeeper Grzegorz Szamotulski.

Szamotulski's contract expires at the end of December and three English Championship clubs have been in touch with agents acting for the keeper as he prepares to leave United.

A couple of Premiership outfits have also shown tentative interest in the man who won 13 senior international caps for Poland, so there is a danger Celtic could miss out.
