Potter narrowly missed out on selection for UEFA Women's Euro 2005, but was recalled straight after the tournament following impressive performances for the U21 team. She scored against Hungary during England's record 13–0 win in October 2005. Potter withdrew from the World Cup qualifying play-off against France in September 2006 with damaged ankle ligaments. However, she returned to the team for the 1–0 friendly win over Scotland in March 2007.
