On 25 February 2020 and after coaching the reserve team for 3 seasons, Haise became the head coach of Lens, following the dismissal of Philippe Montanier.[3]
On 27 May 2023, he led Lens to win 3–0 against Ajaccio in the 38th and final matchweek and qualify for the Champions League for the third time in their history after 1998–99 and 2002–03, finishing with 84 points only 1 point behind Paris Saint-Germain.[4] On 6 June 2024, he became the head coach of fellow French club Nice.[5]
Coaching style
Haise has generally set up Lens in a 3-4-1-2 formation,[6] although he has at times used a 3-5-2[7][8] and a 3-4-3.[9]
Despite mainly using a back three at Lens, he has stated, "I don’t have a favourite system. For some time now, we have often played 3-4-1-2 or 3-5-2 with the midfielder moving. This is the one I use because it more closely matches the squad and the players".[6]
