Saudi side Al-Ahli have reportedly offered Marco Silva a two-year deal worth £40million to leave Fulham this summer.
The Portuguese manager has 12 months left on his current deal at Craven Cottage.
Fulham have tabled a new deal but Silva has doubts over whether to commit his immediate future to the west London side despite their impressive top-half finish last season.
Should he make the move, he would become the first serving Premier League boss to be tempted away by the Saudi Pro League.
Silva is currently in the US as part of Fulham's pre-season tour.
