Floyd Mayweather vs Conor McGregor.

We are only 25 days away now from the biggest spectacle in boxing and UFC history as Notorious crosses the divide and enters the boxing ring for the first time in his career.

Whether it will be his last encounter in a boxing ring is unknown, but one thing is for sure, it will certainly be his biggest, which would lead you to believe it will be his one and only boxing match.

Although there has been plenty of critics regarding the super fight, which several figures within the sport labelling it a joke and a circus, McGregor is taking this seriously.

He's hired former professional boxer Paulie Malignaggi as his sparring partner, and he's also brought in professional boxing referee Joe Cortez to help him come to terms with the rules of the sport.

Of course, this will be Notorious' first time competing in a boxing-style fight. He's used to takedowns, flying elbows, and roundhouse kicks. None of which will be allowed come August 26.

Unlike McGregor, Mayweather has made his career inside the ring. He's fought 49 professional fights, winning them all. He knows boxing like the back of his hand, and that's why he's the firm favourite.

However, with expectation comes more pressure. Some say it's a lose-lose situation for the American. If he wins, it's expected, if he loses, he's a laughing stock.

And that is something that he's been warned about by former boxer Carl Froch.

Speaking to Sky Sports News, Froch issues a severe warning to Money, telling him to not embarrass boxing or let the sport down by losing to McGregor.

He said: "Anybody who knows anything about boxing doesn't give Conor McGregor a chance.

"I thoroughly expect Floyd Mayweather to win, but he'd better not let the world of boxing down. I hope he wins it for boxing but this is an amazing event and I can't wait for it.

"McGregor's got to land something, a punch, quite hard and hurtful early on to be within any chance but anyone who knows boxing isn't giving him a chance.

"This is a Mission: Impossible."

However, Froch has given McGregor some hope, by admitting that age may play a part come fight night.

"McGregor is 29 against a guy who is 40 - a little bit older than me - and he's been retired for a couple of years. You really do 'feel' you're retired, you become civilised and soft and you lose that fighting mentality," he said.

"Floyd has brittle hands, so how is the training camp going to go? I am just looking for some positives for Conor here and Mayweather isn't the Mayweather we know from two, three, four, five years ago when he was the best of the best.

"We are just going to have to wait and see."
