On 30 March 2009 Dede signed a one-year contract to play for Arna-Bjørnar in Bergen, Norway. She had been brought in following an injury to fellow goalkeeper Erika Skarbø.[3]
She had initially considered retiring from international football following the 2014 African Women's Championship, but was convinced to continue playing through the 2015 World Cup. Following the tournament, she announced her retirement in March 2016, having played 99 games for the senior national team.[7] At the time of her retirement, she had been the longest serving player for the squad, and had recently been dropped from the team for the qualification tournament for the 2016 Summer Olympics.[6]
She decided to fully retire from professional football in October that year, saying "I cherish the opportunity to play at club level and represent my country, it was a dream come true. I am very grateful to have spent over a decade in female football, I owe so much to the best game in the world."[8]
