Nypan made headlines in Norway for his rapid rise through the ranks. At just 15 years and 322 days old, he debuted in the Norwegian top division, becoming one of the youngest players in Eliteserien history, just over 200 days older than Arsenal skipper Martin Odegaard when he made his own debut.
Since breaking into the Rosenborg first team, Nypan has gone on to make 70 senior appearances. During the 2024 season, he scored eight goals and provided six assists, becoming one of the standout performers for the Trondheim-based side.
