[3][4] Hansen was a player of great stamina and positional sense with good technique, and his game was riskless without surprise or use of trickery, but also without mistakes.

At the 1960 Olympics, he played in the position of right halfback on the Danish team, often linking up via short passes with right-winger Poul Pedersen.

[6] Hansen played all five games as Denmark won silver medals, losing to the Yugoslavia national football team in the final.

[7] Hansen stayed an amateur, and played both games, as the Danish team finished fourth at the 1964 European Nations' Cup.

On 29 November 1964 he broke Poul Pedersen's record as he became the first Dane to play 51 games for the national team.
