Fulham, who missed out on promotion in last year's play-off semi-finals, have endured a difficult campaign so far and are currently languishing down in 17th position.
Manager Slavisa Jokanovic is said to be under slight pressure to turn things around and there are now reports suggesting he will look to delve into the market when the January window opens.
Netherlands Under-21 international Ayoub has been linked with the Cottagers and the fact his contract runs out at the end of the season could force through a cut-price deal at the turn of the year.
The winger, who has been with the Dutch side since 2008 when joining the youth ranks, has been in impressive form this term and has scored one goal from 11 Eredivisie appearances.
Fulham are believed to have sent scouts on numerous occasions to watch Ayoub in action and will will look to wrap up a deal in the next transfer window.
