Celtic boss Neil Lennon will reportedly move for Sunderland goalkeeper Craig Gordon at the end of the season.
The 29-year-old, a £9m signing from Hearts, is out of contract in the summer and is expected to leave the Black Cats, according to The Sun.
Lennon is also interested in securing Newcastle United goalkeeper Fraser Forster as he prepares his squad for next season.
Celtic have already secured the Scottish Premier League title this season.
