Jacob Ondrejka, a 23-year-old right-footed player, is currently under contract with Parma until mid-2029. He previously played for Landskrona BoIS and IF Elfsborg in Sweden before joining Royal Antwerp FC in 2023. During his time at Royal Antwerp FC, Ondrejka scored 12 goals and provided 8 assists in 55 official matches. He was subsequently transferred to Parma in January 2025 for 6.8 million euros.

Ondrejka made his debut for Sweden on January 12, 2023, in a 1-2 win over Iceland. FC Groningen is looking to strengthen their squad after the departure of Younes Taha and has already signed several players this summer, including Pelle Clement, Rijk Janse, Nikolas Brandis, and Alvin Nordin. Travis Hernes was permanently signed last season, while Tygo Land and Malcolm Jeng will be loaned by the club next season.
