Swansea City are resigned to losing Alfie Mawson and Lukasz Fabianski and have informed both players, who have expressed a desire to return to the Premier League, they will not stand in their way provided their valuation is met.

Mawson is attracting interest from Premier League clubs, including West Ham and Southampton, and is expected to command a £20m fee. That valuation would almost certainly have been higher if Mawson had represented England when he was called into Gareth Southgate’s squad in March, or if Swansea had retained their Premier League status and been in a stronger position to fend off offers for the central defender.

Although Tottenham Hotspur have been linked with Mawson, there is no indication Mauricio Pochettino is interested in signing the 24-year-old, even if Toby Alderweireld ends up moving on. Mawson, who has just had minor knee surgery that rules out any possibility of him being in the England World Cup squad, joined Swansea from Barnsley for £5m in August 2016.

Fabianski was Swansea’s best player by a distance this season and it is understood Watford, Newcastle, Crystal Palace and West Ham are monitoring the Poland goalkeeper’s situation. The 33-year-old, who joined Swansea on a free from Arsenal in 2014 and has 12 months left on his contract, is likely to be available for about £5m. Although there has been interest from top-six clubs keen on bringing in an experienced and reliable No 2, Fabianski wants to be a first-choice goalkeeper.

Swansea are preparing to turn their attention to the pursuit of a new manager, with Carlos Carvalhal’s departure expected to be confirmed within the next couple of days. Graham Potter, who has enjoyed spectacular success with the Swedish club Ostersund, is a leading candidate, with Swansea focusing on bringing in a young and ambitious coach to re-energise a club that has badly lost its way.
