Swansea accepted Fulham's proposal for central defender Alfi Mawson, reports Sky Sports.
According to the source, the transfer amount will be 20 million pounds, and the 24-year-old Englishman will undergo a medical examination and sign the contract on Tuesday, July 31.
Mawson moved to Swansea in the summer of 2016 from Barnsley for five million pounds.
Last season he was in the starting line-up in all 38 Premier League matches, but his team failed to keep a residence permit in the top flight.
Earlier it became known that Fulham refused to purchase Zinchenko.
