Tale of the Tape
MAYWEATHER heads into the blockbuster bout as clear favourite.
The American bowed out of boxing with a spotless record of 49-0.
In 2015 he defeated Manny Pacquiao, which enhanced his incredible career.
Before retiring, Mayweather fought Andre Berto, in September 2015 to take him just one bout away from his 50th fight.
McGregor's inexperience will certainly show - but physically he has the edge on Mayweather.
The two-time UFC champion has a longer reach and will pack more power in his punches.
And his own record of 21-3 is not half bad either.
McGregor has begun preparation and updated his online followers with a picture of himself wearing boxing gloves during sparring.
Meanwhile, UFC chief Dana White reckons the Irishman will pocket an incredible £78million for the Las Vegas super-fight.
Mayweather hopes to earn at least £231m - the same amount he took home for fighting Pacquiao.
