De Bock arrived at Elland Road from Belgian outfit Club Brugge in January 2018 and the Yorkshire giants hoped he would be the answer to their left-back issues.
However, he struggled to make an impact and was quickly frozen out by Marcelo Bielsa when the Argentine took over.
De Bock has been spending time away from the Yorkshire giants on a succession of loan spells, both abroad and in England.
The 29-year-old is currently on loan at Belgian side Zulte Waregem, his fourth different temporary home and he is in the final year of his contract at Leeds.
And according to Belgian daily Het Laatste Nieuws, De Bock has now put pen-to-paper on a one-year deal at Essevee, with an option to extend his stint by another year.
The left-back has been playing for Zulte Waregem since the summer of 2020, and he has managed to convince them to hand him a permanent deal at the club.
Leeds are currently locked in a relegation battle in the Premier League and the likes of Kalvin Phillips, Raphinha are linked with moves away from the club should they drop down to the Championship.
