Goalkeeper Lukasz Fabianski has told Swansea City he wants to leave this summer following the club's relegation from the Premier League.
The 33-year-old was named supporters' player of the year after a string of impressive displays in 2017-18.
He is settled in south Wales and has a year left on his Swans contract.
But sources close to the Poland international, who joined from Arsenal in 2014, say he wants a transfer to continue at the "highest level".
Centre-back Alfie Mawson has attracted interest from clubs such as West Ham, but the Swans would only consider selling either Mawson or Fabianski for the right price.
