Maurice Steijn, the new manager of ADO Den Haag, has described the possibility of his son, Sem Steijn, a 25-year-old Dutch attacking midfielder, moving to the club during the winter as hopeless. Following Maurice Steijn's appointment, there was speculation about a potential reunion. During his presentation press conference, the manager was asked about winter reinforcements. Algemeen Dagblad cited him as stating that possibilities existed and would be utilized. However, when questioned directly about his son, who has primarily been a substitute at Feyenoord, Steijn said he wished Sem could play for ADO but dismissed the transfer as hopeless, though he understood the reasoning behind the speculation. The Netherlands international, who has one cap, joined Feyenoord in July 2025 and his contract runs until June 2029. His current Transfermarkt market value is €11.00M.
