CELTIC could look to out of contract Dundee United goalkeeper Benjamin Siegrist this summer, according to a report.
The 30-year-old will move on from Tannadice this transfer window and a number of clubs have already been credited with an interest.
Rangers were previously linked with his signature, while some reports stated that Manchester United were also monitoring his situation.
The Daily Mail now state that Ange Postecoglou's Celtic have Siegrist on a list of possible back-up goalkeeping options.
The Hoops are looking for a keeper after Vasilis Barkas exited the club on loan to Dutch side Utrecht for the season ahead.
Barkas signed for £5million from AEK Athens in 2020, as Neil Lennon moved to replace Fraser Forster.
Things haven't worked out for the keeper at all though, with a series of high-profile errors in his debut season costing him his place in the side.
Siegrist on the other hand has been in top form for United and the Terrors were keen for him to stay but could not agree on a deal.
Joe Hart is the current first choice at Parkhead with Scott Bain as his deputy. Conor Hazard is also still on the books, but likely head out on loan this summer.
