Leeds have been in discussions with Brentford over the winger since yesterday, and are now close to striking an agreement.
Leeds are said to be willing to pay £3 million for the winger, who impressed with the Bees last term.
Marcelo Bielsa’s side have been keeping an eye on Jozefzoon for much of the summer so far, but have been forced into action by Derby County.
Frank Lampard’s side have already had a bid accepted for the Dutchman, but Leeds are now looking to challenge for the 27-year-old.
Leeds still have not completed a permanent transfer so far this summer, with Lewis Baker and Jamal Blackman both only arriving on loan.
If Jozefzoon was brought to Elland Road he would increase the creative options available to Bielsa, and add to their pace of Leeds’ attack for next season.
