- Axelsson was a classy fullback with good technique, ball control and touch.
- He was a very elegant type of player and never injured a teammate in his entire career. But he was also never cautioned.
- Nisse Axelsson was not a left back. He played as a right back, but he was the most famous exponent of HIF captain Bill Pettersson's Helsingborg system, which revolutionized soccer at the time and was behind HIF's unprecedented successes.
In practice, this meant that Nisse functioned as a central defender/midfielder, while Nisse Rosén was left free to devote great attention to the game and attack. So if Sporten places Nisse as a left back in this series, it doesn't really matter: his task would not have been significantly different.
- Nils Axelsson was a gentleman on the field, a technical player who did not break the rules. It is said that he never caused a free kick. That's probably not true, but in any case his number was very limited.
- There he became known for an elegant style of play based on good technique, ball control and a good feel for the ball. Axelsson was called “the elegant of the elegant” and played his entire career without being cautioned; however, he scored only one goal for HIF in the 584 games he played for the club.
