During season 2001–02, he transferred to German Borussia Mönchengladbach. Fredrikson was at that time one of the most promising footballers in Finland. He represented Borussia Mönchengladbach until season 2005–06. During the years in Borussia he did not gain any caps in the first team, but did gain 15 caps in the reserves team. During seasons 2004 and 2005 he was loaned to Finnish club FF Jaro where he played 52 matches.

He made 48 appearances in the Russian league before suffering an injury in international friendly match between Finland and Turkey on 2012. He did not re-emerge until 2014, when joining Lørenskog at the Norwegian third tier. In 2015, he signed for Kongsvinger, also a third-tier team, albeit formerly in the Norwegian Premier League. In the summer of 2015 he signed for Vålerenga on an emergency loan deal because Michael Langer was injured and Lars Hirschfeld is playing Gold Cup for Canada.

He made his debut for the Finnish national team on 29 May 2008 against Turkey. After Jussi Jääskeläinen announced his retirement from international football, Fredrikson was the number one choice for Finland.

However, Fredrikson has been away from the squad since May 2012, when he got injured before the friendly match against Turkey.
