In 2022, Slegers transitioned from the youth academy of Genk to Sint-Truiden.[3] His swift progress captured the attention of head coach Bernd Hollerbach.[4][5] Despite Hollerbach's admiration for Slegers, his breakthrough into the first team did not materialize, and the board opted not to renew his contract.[6]
On 20 June 2023, he joined Dutch second-tier Eerste Divisie club MVV, signing a two-year contract with an option for a third.[3][7] His professional debut for the club's first team came on 13 August 2023. In the opening match of the Eerste Divisie season against VVV-Venlo, ending in a 3–1 victory, Slegers earned a starting position under coach Maurice Verberne. He scored the opening goal shortly after halftime and was substituted in the 72nd minute for Dailon Livramento.[8][9]
