Swansea City have enquired about former Liverpool defender Martin Skrtel.
Manager Paul Clement is looking to add some experience to his defence and has also held talks with free agent John Terry.
Fenerbahce paid £5million for Skrtel and will look to recoup most of that as they prepare to sell the 32-year-old.
Swansea are braced for interest in England Under 21 international Alfie Mawson who has impressed since joining from Barnsley for £5.5million last August.
Mawson scored for the Young Lions to set them on a comeback victory over Slovakia at Euro 2017 on Monday.
