Career
Mortensen was a striker who played for Aarhus Gymnastikforening, Anderlecht, and Norwich City. During his early career, he was voted Danish young player of the year and was capped by Denmark under-21s. Dave Stringer signed him for Norwich for a fee of £350,000 shortly after the start of the 1989-1990 season.
The move generated considerable interest among Norwich supporters, and a large crowd saw him mark his debut for the club"s reserves at Carrow Road by scoring a spectacular overhead kick.
Mortensen scored on his first team debut in a Zenith Data Systems Cup match against Brighton but was unable to maintain his impressive start. An injury forced him to retire from the English game in 1991.
