Manchester City goalkeeper Claudio Bravo is regarded as an option for Celtic in the transfer window.
The Chilean legend appears on a transfer shortlist of 11 names, including other Premier League goalkeepers Joe Hart and Ben Foster.
All three are out of contract this summer.
Neil Lennon is keen on retaining Fraser Forster after his loan spell from Southampton ends, but the giant Englishman is on a lucrative contract which doesn’t end until 2022.
The club currently have Scott Bain contracted until 2023, while Craig Gordon’s contract was due to expire at the end of May but there has been no confirmation of a departure or new deal.
The Times of Chile report Bravo is a prominent name on Celtic’s list as they seek to “perform major surgery to their squad”, according to the paper.
The 37-year-old is hopeful of staying at Manchester City with the extension to the Premier League season likely complicating matters for the Scottish champions and their recruitment.
Bravo is a hugely decorated goalkeeper. He has 123 caps for Chile – the third most in the country’s history – and lifted the Copa America twice. He has won titles in Spain with Barcelona, in England and in his homeland with Colo Colo.
Meanwhile, Ben Foster is now 37 and has been a regular for Watford after moving from West Brom. He has amassed more than 300 Premier League appearances.
Hart is a two-time Premier League winner and has 75 caps. The 33-year-old, however, has had adifficult time in recent years, with loan spells at West Ham and Torino, while he hasn’t played in the Premier League for Burnley this campaign.
