In just under a month's time, boxer Floyd Mayweather and mixed martial artist Conor McGregor will come face to face in an unprecedented showdown.

It will be the first time a boxer and mixed martial artist will fight each other and the clash is seen by many as probably the biggest fight of all time.

Floyd Mayweather is coming out of retirement, while for McGregor, this will be his first fight since defeating Eddie Alvarez in November 2016.

The usual pre-fight hype has seen both fighters exchanging choice words as well as the expected personal insult.

As the fight draws even closer, however, both fighters have found even more imaginative ways to sell the fight and fire shots at each other. 

Both fighters are still heavily involved in the selling of the fight and were both stars in a own promotional video, part of TV advertising campaign for SHOWTIME.

In one video, Mayweather looks to the screen and says: “Hey you – yeah you, it’s the one and only ladies and gentlemen, it’s Floyd ‘Money’ Mayweather. I’ve never been beat. NEVER. I’m knocking McGregor the f*** out.”

In McGregor's video, he says: “I’m Conor McGregor, there’s only one man I want to fight, going on to say “Floyd might be undefeated, I’m ready to shock the world.”

Both fighters are without doubt the best in their respective crafts and the fight between the two is one that many boxing and UFC fans are keen to witness.

It is not only a clash between the two fighters, but it is also a battle between boxing and the UFC. 

It certainly will be a fascinating showdown and it is widely thought Mayweather, with his vastly superior boxing prowess and experience, will come out on top.

With the fight taking place in a boxing ring, the advantages are stacked on Maywether's side. The American is also, arguably, one of the best defensive fighters of all time.

His movement and fast hands have caused many a previous opponent a myriad of problems. He retired having been undefeated in 49 fights and that record more than underlines his superior skill set.

At the same time, Notorious is also a highly skilled, hard hitting fighter, and should not be discounted.

In the UFC, he is a highly regarded, slick combatant who has taken the popularity of the sport to a new level.

In many respects, he is almost Maywether's UFC equivalent in terms of skill level, impact on the sport, and popularity.

The fight cannot come soon enough.
