The UFC light heavyweight has just suffered his second defeat in his quest to become the UFC light heavyweight champion.
But after putting on two spectacular performances the Swede insists he is no ‘journeyman’ and the UFC and Dana white has ‘big plans’ for his future.
"I will continue as long as I know I have the potential to be the best," Gustafsson told Swedish outlet Allehanda.

"The Mauler" went on a six-win undefeated streak from 2010 to 2012, but the giant has since fallen to Jon Jones, Anthony Johnson and Daniel Cormier.
"If there comes a day where I feel I can not go any further than this, that day I stop. Then I put the gloves on the shelf. But I feel that there's more to achieve."
"I know I can be better. I know I have the potential to beat 'DC'. I know I can beat Jon Jones."
2015 will be a year to forget for Gustafsson after suffering the first KO of his career in the first round by Anthony Johnson at UFC on FOX 14 in January.
With a lack of contenders for the title, Gustafsson battled newly crowned champion Daniel Cormier on October 3, losing via split decision:
"I do not want to be a journeyman," said Gustafsson.
"I do not want to be a fighter that people should beat to get a title fight. I do not want to be in fights where people see me as an obstacle on the road.
"I want to be the man challenging. I'm not satisfied with being ranked second and third. I'm such a self-critic, that I find it hard to give myself credit for something."
"Sure, it was a good fight against DC. It was a good fight against Jones, but I didn't win. So that is not a good fight. It is not enough that I've put Sweden on the map. I've heard a hundred times how good that was.
"I appreciate what people say to me and that they give me credit. But for my personally, it's not enough. I want to go all the way."
Gustafsson is still well regarded as one of the best talents to come out of the UFC from Europe, along with the likes of “The Notorious” Conor Mcgregor, and Micheal “The Count” Bisping, and he doesn’t sound worried about his own future with the UFC.
"We'll see what the future looks like now," Gustafsson said.
"I spoke to Dana White and Lorenzo Fertitta on Friday. 'Big plans', was all they said. We'll see what they have to offer. I am 28 and I see myself involved with this a few more years. I want to go some more years."
