Csepregi György, the Hungarian sporting director of OH Leuven, stated that following negotiations with Kyan Vaesen and his representatives, an agreement was reached and the player signed with the club. Footy Belgium reported that Vaesen is leaving Westerlo for OH Leuven, choosing a move within his own country over a transfer to Újpest. At Den Dreef, he hopes to get more playing time and begin a new phase of his career.

Voetbalnieuws.be reports that Kyan Vaesen has moved from KVC Westerlo to OH Leuven and signed a contract until mid-2029. Vaesen had the option to move abroad but chose to stay in Belgium. He was not receiving playing time at KVC Westerlo.

Pieter-Jan Calcoen confirms that OH Leuven will acquire Kyan Vaesen. Vaesen is a Belgian centre-forward who was considered not needed at Westerlo because he was unable to secure a regular starting position. The 24-year-old's chances of playing were further reduced following the arrival of fellow attackers Afonso Patrão and Enis Destan. According to Het Nieuwsblad, Vaesen is set to sign a multi-year contract with OH Leuven. He will be the club's first winter signing and will compete with Kaba and Ikwuemesi for a spot in the attack. In the current Jupiler Pro League season, Vaesen has made 19 appearances, scoring one goal and providing one assist. He has 2 caps and 1 goal for the Belgium U21 national team, and his current Transfermarkt market value is €700k.
