Conor Mcgregor says he'll knock Mayweather out within 4 rounds at their latest press conference in LA - Watch!

I can't believe this fight is actually gonna happen! The UFC's best ever pound-for-pound champion vs Boxing's pound-for-pound best ever champion. And it will in August. Unbelievable.

Mcgregor is confident as always and the superstar of MMA. Mayweather is the epitome of self belief and undefeated in 19 years of boxing.

Many have said Mcgregor has no chance in a boxing match with Floyd, and common sense says I must agree. BUT, and this is a huge BUT, where is the common sense in a match like this? Who really thought this would ever happen? And we are talking about Mcgregor here, who time and time again has done the seemingly impossible. Floyd is 40 years old now. He's never been in a real fight, he's had boxing matches, which as Conor says is only a quarter of a fight, a semi-fight. Mcgregor is the bigger man, he's stronger and has the power in that infamous left of his to put Mayweather to sleep on the canvas. Mcgregor is not stupid, he knows what he's facing in the form of Mayweather. He will adapt, he'll look to finish early (inside 4 rounds according to his own prediction). His understanding of space and his fight IQ are rediculous and if anyone can do the impssible, it will be Mcgregor.

I cannot wait!
