Leuven head coach Vincent Euvrard and football adviser Frank Vercauteren have signed three-year contracts with the club.
The duo took up their roles on 8 February following the sacking of Nigel Pearson and lifted relegation-threatened Leuven to safety in the second tier.
Euvrard and Vercauteren worked together at Cercle Brugge and will now look to match the ambition of Khun Aiyawatt Srivaddhanaprabha by taking Leuven to the next level.
Leuven CEO Peter Willems said: “We are satisfied that we can continue the excellent cooperation with Frank and Vincent. We are counting on the fact that with this duo we can continue on the chosen path to achieve our common goal. ”
