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"
