Liverpool goalkeeper Simon Mignolet is set to join Besiktas in a £12 million deal.
The arrival of Alisson Becker means that Mignolet is now the third choice keeper, when he was first choice a year ago.
He has no option but to leave the Anfield club. The Sun reports that Besiktas are offering him a route out.
The 30-year-old would be the second keeper to leave since Alisson joined the Reds, with Danny Ward departing for Leicester City.
