Sunderland goalkeeper Craig Gordon could leave the club on a free transfer this summer.
The Scotland international signed for the Black Cats in 2007 for £9 million. At the time the fee was a British transfer record for a goalkeeper.
However, repeated injury and the form of Belgian keeper Simon Mignolet has led to Gordon falling out of favour at the Stadium of Light.
The 29-year-old is now coming to the end of his contract and is widely expected to move elsewhere, with Scottish champions Celtic reportedly interested.
Last week, Gordon won the Premier League's best ever save award for his stop against Bolton in December 2010.
