Winger completes transfer.
Leeds United can today confirm that we have completed our first capture of the summer transfer window.
Hadi Sacko, who enjoyed a successful loan spell with the Whites last season, has now agreed a permanent move to Elland Road.
The Frenchman joins the club from Portuguese Primeira Liga outfit Sporting Lisbon.
Sacko has penned a three year contract with Leeds, tying him to the club until at least the end of the 2019/20 season.
After coming through the ranks with French outfit Bordeaux, where he made 11 appearances, Sacko was snapped up by Sporting in 2014.
Last season the 23 year-old spent the full campaign with the Whites on a temporary deal and made 42 appearances in all competitions, as Leeds finished in seventh place in the Sky Bet Championship.
The loan deal included an option for the club to sign Sacko permanently and that option has been triggered.
Known for his lightning pace and trickery, the winger proved to be an exciting addition to the squad last season, causing issues for a number of opposition defences during the campaign.
He scored two goals for the Whites during the 2016/17 campaign, netting in the 2-1 home defeat against Birmingham City last August and the 4-1 away victory over Preston North End on Boxing Day.
Sacko becomes the first permanent transfer completed by new owner and Chairman Andrea Radrizzani.
Speaking about the signing, Leeds United Managing Director Angus Kinnear said: “We are delighted to announce the signing of Hadi today, he is an exciting player with great potential and a player we hope to see develop over the next three years.”
