Leeds have triggered a clause in the loan agreement of Sporting winger Hadi Sacko to sign him permanently, Record have reported.
The Championship club will pay £1.5m for a player that spent last season on-loan, and divided the opinion of fans to an extent.
The Frenchman made 38 appearances in the league for Leeds, scoring just twice and providing three assists.
Leeds reportedly hoped to negotiate the fee down from the original price set in the loan agreement, but Sporting have remained stubborn.
At 23-years-old, the club still view Sacko as a player with potential despite some raw performances in his first season of English football.
Record claim that the deal will be finalised next week, with Leeds eager to make the loan move a permanent one.
The Yorkshire club are also looking to appoint a new manager after the unexpected resignation of Garry Monk on Thursday.
Whoever takes the place of Monk will be faced with the task of reaching the playoffs, a feat narrowly missed out on last season, as well as getting the best out of the somewhat mercurial Sacko.
Sacko has featured for the French national team through all the youth squads up to under-20 level.
