Finnish international Jonatan Johansson joined Norwich City on loan from Charlton Athletic on 31st January 2006 until the end of the 2005/6 season. Nigel Worthington admitted that "Johansson is a player we have monitored for some time - but the scenario would need to be right for things to happen.”

JJ, as he is known at the Valley, joined Charlton from Rangers in July 2000. The Finnish international had scored 24 goals in just 36 starts at Ibrox, and ended his first season in the Premiership as the Addicks' top scorer with 14 goals. However his goal scoring tally had slipped. During 2004/5, he scored four times in thirty starts -and two of those were against Norwich. During 2005/6 the signing of Darren Bent had limited his chances and he had made just six appearances, scoring once. His record for Charlton reads 33 goals in 167 games while he has scored nine times in 43 outings for his country. He began his career with Finnish sides TPS and Flora before joining Rangers in 1997.

He made his Norwich debut as a substitute in the 4-0 away defeat to Reading on 31st January 2006.His full debut came on 5th February in the 2-1 defeat to Ipswich at Carrow Road. Jonatan scored Norwich's goal.

Returning to the Valley at the end of his loan, he was released along with Shaun Bartlett and Francis Jeffers in May 2006 when their contacts came to an end. Although it was though that Norwich would add JJ to their squad, instead he signed for Swedish side Malmo in eary July 2006.

On 31st January 2008, the Scotsman reported that "Hibs are thought to have had a £150,000 bid rejected for former Rangers striker Jonatan Johansson, who now plays for Malmo"

Hibs finally got their man when they announced in mid-November 2008 that they had signed a pre-contract agreement with Finnish international striker Jonatan Johansson. He will join the Edinburgh side in January 2009 once his contract with Swedish side Malmo expires. JJ joined Hibs on 1st January 2009 and made his debut two days later against Hearts in the Edinburgh Derby.

Along with David van Zanten and Patrick Deane, Johansson was released by Hibs on 1st September 2009. He signed a short-term contract with St Johnstone on 27th October 2009 until January 2010. After 5 appearances and 1 goal for St Johnstone, he was released on 7th January 2010 and is expected to sign for Greenock Morton.
