A light-heavyweight between Alexander Gustafsson (15-1 MMA, 7-1 UFC) and former Strikeforce champion Gegard Mousasi (33-3-2 MMA, 0-0 UFC) is targeted as the headliner of an April 6 event in Sweden, likely to be UFC on FUEL TV 9.

Gustafsson announced the fight at a gym opening today, according to a report from mmaviking.com. On Friday a source close to the event told MMAjunkie.com (www.mmajunkie.com) the bout was possible but not official.

UFC on FUEL TV 9 is expected to take place at Ericsson Globe Arena in Stockholm, which also hosted UFC on FUEL TV 2 in April 2012.

That event, which saw the Swedish-born Gustafsson earn a dominant win over Thiago Silva in the headliner, drew an announced attendance of 15,428 and set a venue record for a sporting event with a $2.23 million gate, according to UFC officials.

Gustafsson currently is riding a six-fight win streak. In addition to Silva, recent wins have come over the likes of former champ Mauricio “Shogun” Rua, veteran Vladimir Matyushenko and Matt Hamill. Gustafsson’s only career loss came in his second UFC fight when he suffered a submission defeat to Phil Davis, who’s now one of his primary training partners.

The Swede will look to continue his march toward a title shot when he meets Mousasi, an experienced Dutch fighter who recently closed out his Strikeforce career with a submission victory over Mike Kyle a week ago. The fighter, who’s also competed for organizations such as DREAM and PRIDE, is undefeated (5-0-1) in his past six fights, and he’s 20-1-1 since 2006. The lone defeat came to Muhammed “King Mo” Lawal in a 2010 Strikeforce title fight.
