Fulham winger Willian is wanted by Saudi Pro League club Al Shabab, who are prepared to pay him £200,000 a week after tax.
Marco Silva's side, who are chasing Chelsea's Callum Hudson-Odoi and Demarai Gray of Everton, are yet to receive a bid, however.
Willian signed a new one-year contract only two weeks ago.
The 34-year-old, formerly of Chelsea and Arsenal, scored five goals and registered six assists in 27 Premier League appearances for the Cottagers last season.
After his initial deal ran down, Willian is said to have held talks with Nottingham Forest over a potential move and even visited their training ground.
