Career
Sundell refereed a total of 262 Allsvenskan games, the Swedish top tier in football, in 22 years. He also refereed 100 international games during his career. Two of those were matches played during the 1996 Union of European Football Associations European Football Championship in England.
In the quarter-final Germany versus Croatia (2:1) he gave a penalty kick and a red card against Croatia.
Both decisions proved to be correct, even though he did a very poor job that match, and made substantial damage to Croatia.
