The American known as Money and the Irishman called The Notorious have named the place: The T-Mobile Arena in Las Vegas. They have chosen the weapons: Boxing gloves.
They have named their own price: $100million each, although in reality McGregor will have to settle for less and give his UFC masters a slice of the action.
Mayweather has announced that he is officially coming out of retirement to battle McGregor, who says he wants this war more than any other.
So the event they would like to label The Fight of the Century does look like happening.
More accurately, not least given Mayweather’s pseudonym, it is The Money Maker Of All Time.
Even if it lasts no longer than the time it takes McGregor to blink as Mayweather clocks him, this mix-match of the most lucrative marketeers in the noble art and the cage rage will surely smash all box-office records for combat sports. Which is the principal object.
The other, for Mayweather, is that it offers him a clever way of eclipsing the record of retiring on 49 wins and no defeats which he currently shares with the legendary Rocky Marciano.
When it comes purely to boxing, McGregor as an exponent of mixed martial arts is a virtual novice.
All of which begs the question of whether he has any chance at all against the boxer who calls himself The Best Ever.
To be perfectly honest, he does not.
His best hope would appear to be that Mayweather takes victory for granted and goes easy on the training.
Even that seems unlikely, since the Money mantra has always been ‘hard work, dedication.’
Mayweather did tarry in the UK before travelling to Prague on the latest leg of a world tour which began soon after he hung up the gloves in September 2015.
