Edman earned 57 caps for Sweden from his debut in 2001, and was selected for two FIFA World Cups and Euro 2004.
Edman is an experienced left back, who has played for a number of clubs during his career. Edman was a player at Helsingborgs IF until 1999, which was his first time leaving Sweden and moved abroad. In 2001, after having unremarkable spells at Italian club Torino and Karlsruher SC in Germany, Edman returned to Sweden and joined AIK for one season. After that, Heerenveen in the Netherlands brought Edman from Sweden.
In July 2004, Tottenham Hotspur signed Edman from Heerenveen. Edman quickly established himself at the club, and will probably be best remembered at Spurs for his stunning goal, which he scored from 38.17 yards out, in the Premier League match against Liverpool in April 2005. However, in the summer of 2005, the arrival of South Korean left back, Lee Young-Pyo, led Edman to make the decision of leaving England.
In the last week of August, Spurs accepted an offer from French club Rennes. It did not take long for Edman to impress his new manager, László Bölöni, and once again established himself as first choice at left-back.
In January 2008, Edman was signed by Wigan Athletic for a transfer fee of £500,000. The arrival of Edman was a good deal for Wigan Athletic, since the club did not find a good replacement after the departure of Leighton Baines, the previous summer. In March 2008, Edman was injured in a match against Blackburn Rovers, damaging his anterior crutiate ligament in his knee. This means he missed the rest of Wigan's season, as well as Euro 2008. Edman made his return to the Wigan team, as a substitute in January 2009 at Old Trafford, as Wigan lost 1–0 to Manchester United. However, he has lacked playing time, due to injuries and Maynor Figueroa's impressive performances throughout the season, which have earned him a spot in Roberto Martínez's starting eleven. Edman played his last game in the Latics' 9–1 loss against Tottenham Hotspur in November, where he had a torrid time against Aaron Lennon.
On 5 February 2010, Helsingborgs IF confirmed that they had resigned Edman. Edman signed a five-year contract with the Swedish club.
Edman has been a part of the Swedish national team setup, since 2001. In 2002, he was part of the 2002 World Cup squad, but did not make any appearance and was only an unused substitute. He then began to feature more regularly after the 2002 World Cup, and at Euro 2004 and the 2006 World Cup, he started almost all of Sweden's games. He now has a huge amount of experience, with over 50 international caps to his name.
He scored his first and only goal, a free kick, in a 2006 World Cup qualifier against Bulgaria at the Vasil Levski National Stadium in March 2005.Scores and results list Sweden's goal tally first.
