Broholm made the transfer from Rosenborg to LOSC Lille for approximately 6 million euros last year, but struggled to secure a regular starting spot. In 14 official matches for LOSC Lille, he scored 2 goals and provided 1 assist. The forward prefers to play on the right wing, where he can use his attacking style to create chances for his team.
Broholm had multiple transfer options, but chose FC Utrecht due to the team's attacking style and his positive conversations with coach Jordy Zuidam and technical director Jordy Zuidam. He also received advice from Norwegian teammates Oliver Braude and Brynjólfur Willumsson to join the Eredivisie.
