Starting her career in Hägglunds IoFK in her native Örnsköldsvik, she joined Umeå IK in 1995, playing in Damallsvenskan, the highest division of women's football in Sweden. In 2000 she won her first Swedish Championship with the club, and in the following year received the Diamantbollen,[5] the Swedish Football Association's annual prize to the woman player of the year. She also won the Midfielder of the Year in 2003–2005. In 2002 she became the captain of Umeå IK, and in 2003 and 2004, she won the UEFA Women's Cup with the team.
When Moström retired after the 2006 season, Umeå IK retired the number six shirt in her honour. The following season she made a brief comeback, to cover for injuries to Johanna Frisk and Hanna Ljungberg.[6]
In April 2019, she was recognised with the inaugural 'One Club Woman' award by Spanish club Athletic Bilbao for her achievements and loyalty to Umeå.[7]
International career
On 26 July 1998 Moström made her senior debut for Sweden in a friendly against England at Victoria Road, Dagenham. Entering the game as a substitute, she spoiled Hope Powell's first match as England manager by scoring the only goal on 84 minutes.
As a national team player, she has played more than 110 national fixtures, and was one of the most important players when the national team won the silver medal at the FIFA Women's World Cup 2003. Moström's 79th-minute goal against Canada in the Semi-Final of that tournament tied the match and kept Swedish hopes alive.[8] In the 2004 Olympic football tournament she scored a match-winning goal against Nigeria in the final round of the group stage, which took Sweden to the quarter final.
