United had made a poor start to the 1964-65 First Division season and appeared to be heading towards relegation, which would have undone the great work done by Kerr since leading the team to promotion in 1959-60.
Kerr had taken a gamble in bringing players with no experience in Scottish football, like Mogens Berg and Lennart Wing, to the club to help fight relegation.
The gamble paid off, and Persson's classy play on the wing and pinpoint crosses being complementary to Døssing's huge goal scoring talent.
He has the distinction (shared with fellow countryman Lennart Wing) of being the first Dundee United player to win a full international cap.
He moved to Rangers in May 1967 where he played 113 games, scored 31 goals (often spectacular ones) and won 6 caps, representing his country at the World Cup in 1970.
