The super-fight Conor McGregor v Floyd Mayweather will take place in August. Here's all you need to know about the fight, including boxing journalists' predictions, free betting tips, betting odds and how to watch.
McGregor v Mayweather predictions
Leading boxing journalists shared their views on the fight. Here's their McGregor v Mayweather predictions:
"First things first, this is not a great sporting event.
"It is two of sport's greatest self-publicists coming together to see how many millions they can make through pure hype.
"A great fight was Anthony Joshua against Wladimir Klitschko which proved to be an epic event, which lived up to the hype. As a contest, this will come nowhere near that.
"For all of Conor McGregor's brash talk, he's not a boxer. He had a few fights as a amateur, growing up in his native Dublin before he took up cage fighting.
"This should be a mismatch, even if Floyd Mayweather Junior is coming out of retirement.
"The build-up is proving to be hugely entertaining - if two blokes standing trading insults and making rude gestures is your kind of thing"
"Few of Mayweather's opponents ever landed a glove on him because he is so elusive. He is a ghost and is a master of the art of boxing, which is hitting without being hit.
"But he's never been a big puncher, being content to counter-punch opponents on his way to points wins. That gives McGregor a chance and success for him would be to take Mayweather the distance.
"I can see that happening and he is strong, gutsy and aggressive. But McGregor beating Mayweather - get real!
"Yes, McGregor is a two-weight world champ at UFC and is younger.
"But boxing and MMA are two very different sports and Mayweather does not plan to engage McGregor. He will do what he always does and he will use his unrivalled ring craft to pick off McGregor while keeping out of trouble.
"Mayweather is extremely clever in that he only picks fights he knows he will win. Like fabled Chinese warrior Sun Tsz in the fifth century, he only seeks battle after the victory is won.
"He has done the same with McGregor as he searched for that opponent for that record-breaking 50-0 tally. I just can't see the fight being competitive and for me Mayweather wins every day.
"But the build-up is proving to be hugely entertaining - if two blokes standing trading insults and making rude gestures is your kind of thing.
"Just don't expect the fun to continue when the first bell goes."
"Floyd Mayweather Jnr against Conor McGregor is a massive mismatch. On one side you have the greatest boxer to grace the ring since Sugar Ray Leonard and on the other side you have a professional boxing debutant who has only minimal amateur experience as a novice back in Dublin when he was a teenager. Vasyl Lomachenko had over 300 amateur bouts, won two Olympic gold medals, two world amateur titles and lost just one bout in the unpaid ranks.
"In his second professional bout he challenged for a world title but came up short against Orlando Salido, a very good but not great fighter. So what chance does McGregor have against the best fighter of this generation? Mayweather could end the bout whenever he fancies."
"McGregor is a fantastic character and has a brilliant MMA game, but when it comes to boxing he wouldn’t even win an Irish title. Forget the talk that he his bigger and hits hard, boxing is different to MMA striking. Mayweather can end the mismatch whenever he wants and will get the job done by the halfway point."
"On 26 August, Floyd Mayweather, the greatest defensive boxer of the modern era and undefeated in 49 paid contests, takes on Conor McGregor, a man who has never had a professional fight and would struggle to win an Irish amateur title.
"It's a freak show, a con, an almighty money-spinner and it wouldn't surprise me if they were texting each other throughout the build-up. Mayweather will stop him in the middle rounds."
Jonathan Best, freelance boxing writer
"As I march into my thirties it's getting harder and harder to stay awake for the opening bell of the these American PPVs. I'm intrigued enough by the Mayweather McGregor bout to fill myself full of caffeine and tune in - if only on the off chance that Vince McMahon might burst into the arena and hit one of the pugilists over the head with a steel chair.
"Where Mayweather is concerned the best option is almost always betting on him to win a points decision. but I worry about the Irishman getting disqualified given that Queensbury rules will be a big change for him.
"So I'll go with the total rounds market and take the over on 7.5 rounds @ 5/6 on Unibet."
