Brighton goalkeeper Mat Ryan is being linked with Ange Postecoglou's Celtic.
Sky Sports says Celtic are considering a move for Ryan.
The Australian international spent the second half of last season out on loan at Arsenal.
Ryan is expected to leave Falmer stadium in this summer's window with one-year left on his current deal.
Sky Sports report that new Celtic boss Postecoglou is keen to work with Ryan again after coaching the 29-year-old at national level.
