He later played for Feyenoord Rotterdam, KFC Winterslag and Olympiakos, before he returned to Norway in 1985, making his debut in the Norwegian Premier League for Rosenborg.
Albertsen made his debut for the club in 1975, and soon became a regular in the Den Haag lineup, earning praise for his tireless running and no–nonsense physical play.
He was a member of the Rosenborg side that won the title in dramatic fashion in 1985, and played two more years at the Trondheim club before retiring because of injury at the end of the 1987 season.
Many remember him from the famous match against England in 1981, where he was awarded the 1–1 goal, despite that television replays have later shown that Albertsen did in fact not touch the ball, and Tom Lund's cross went straight into the net.
Roger Albertsen was a hard-working and hard-tackling midfielder who never truly established himself as a first-choice in the Norway lineup, but he was a dependable player who did a fine job whenever he got the chance.
After retiring from the game, Albertsen worked in the computer business, and also held coaching jobs for lower-division sides Sistranda, Orkanger, Sokna and Kongsberg.
