United have been linked with a £500,000 bid for the 24-year-old, with the club keen to bolster their creative options ahead of the summer transfer window closing at 6pm on Tuesday.
The Dutchman, 24, is one of several players being considered by Leeds, who have ended their interest in Watford’s Fernando Forestieri and are also keen on Nijmegen’s Belgian winger Anthony Limbombe.
Meanwhile, the agency representing United defender Guiseppe Bellusci have stressed that his client wants to remain at the club amid rumours of a return to his homeland.
Atalanta and Bologna are being linked with a move for the 26-year-old, who moved to Leeds from Catania for a £1.6m fee last August.
Bellusci has started three games for United this season and his representatives have stressed to the YEP that he is happy at the club..
