So, why can Anderson Silvak challenge a fighter – sorry, a phenomenon – because he can not win it anybody else?
"Because that is a fight," the great Brazilian said Israel Adesanya in his UFC 234 imperial show, "will be the biggest UFC history."
"Every fight will be the tallest of our time," says Silva.
Now you will probably understand this, they are some claims.
Even though your fighting knowledge is no less deep than the Irish whiskey of Conor McGregor.
Silva is undoubtedly the biggest UFC fighter – and Adesanya is undoubtedly the best future ever, after six years, as the Brazilian title is famous and Sunday's Rod Laver Arena has appeared.
Worse, the UFC legends lasted two years, though they fought, to a large extent, by the USADA forced suspicions for drug use, the second.
He added 43 years and it is easy to understand why Silva $ 4.75 outsider against his old car.
And the younger, stronger and faster doppelganger.
So why are Brazil's confidence?
Well, in the beginning, it's still Anderson Silva.
That, and arguably for the first time in his career, is a great fight, even if a competitor (on paper – at least) looks at the higher stand-up game.
Which calms may be older but not necessarily.
And after 20 years, Silva has been trying to keep up the fight for opponents, for firing against damage, fighting for anything on the ground.
But on Sunday's week in Melbourne, this is not a problem.
No, standing up and banging, Adesanie did nothing but four UFC appearances and 15 battles.
What is GOAT what you want, right?
"Oh, I've been convinced that this fight will be something special," he says, grinning. "Something fans have never seen."
OK, but do you get it from the Aussie land company's second hunger?
Four years ago remembered UFC 193 in Melbourne, Ronda Rousey was seemingly perfect for Holly Holm, with $ 11 outsider, through sports.
In fact, Silva needs to win, not only breaks the library, but has won a UFC halftime break, and Aussie Rob Whittaker defends the same card against Kelvin Gastelum.
So, again, will he be a guy?
"Obviously, it's a big win," says Silva. "But for me, it's the second one.
"I think for myself, for my fans, it's not an Underdog to win, or even win, it's something special.
"And I think that this fight will be unique … the best in the world."
