HAFTHOR BJORNSSON demanded a fight contract from Tyson Fury in response to their latest verbal sparring session.
Fury took an impromptu flight out to Iceland with his dad John and business partner Spencer Brown.
And their mission was to "find" Game of Thrones star Bjornsson following talk of an exhibition bout.
But after failing, Fury said: "Thor, considering you're not here and you've left Iceland to me, I am the new Viking.
"I own this place now. It's mine."
But Bjornsson hit back: "I'm currently in Rome filming a movie, loving life and guess what?

"Tyson Fury's in Iceland, he tried to find me, couldn't find me because obviously I'm not there.
"But Tyson, if your team is serious, if you're serious about fighting me, have your team send me a contract, lets get serious and I'll find you.
"I'll come to you, I'll find you, no worries."
Bjornsson, 33, recently beat strongman rival Eddie Hall, 34, in their gigantic grudge match in March but he has not returned since.

Fury, 33, meanwhile retired from boxing a month later knocking out Dillian Whyte, 34, at Wembley.
But it appears his hiatus was short-lived after claiming he was coming back to face Derek Chisora, 38, in an unlikely trilogy bout.
The fight was first eyed for December but shortly after, Fury appeared to suggest his rematch with Chisora was already off.
He said: "Do you know the funny this is - people love to do deals and then ask for more or change the goalposts.
"But the usual thing for me is then I tell them to go get f****d. So there we are."
It would free up Fury to fight Bjornsson in a extraordinary exhibition.
With the Gypsy King still keeping hold of his WBC title, an undisputed decider remains on the cards.
But he first has to wait for Oleksandr Usyk, 35, to rematch Anthony Joshua, 32, next Saturday, following the Ukrainian's win last September.
Fury would then be in line to challenge the winner in what would be a first-ever heavyweight unification in the modern four-belt era.
