Millions of people from all four corners of the globe will tune in this Saturday night to watch Floyd Mayweather and Conor McGregor go head-to-head in Las Vegas.

In what is expected to be the most lucrative fight in history, the two superstars will finally walk the walk after months of trash talking.

More than four million pay-per-view (PPV) purchases were made for Mayweather’s victory over Manny Pacquiao two years ago, bringing in nearly $400 million in revenue. It’s expected that Mayweather v McGregor could attract in the region of five million PPV purchases.

Mayweather remains the firm favourite, with just days to go before the fight, although the 40-year-old’s odds have drifted slightly since the event was first announced.

McGregor is priced at around 3/1 with most bookmakers to cause arguably the biggest shock in boxing history.

Joshua's pre-fight message to McGregor and Mayweather

Among those who’ll be tuning in this weekend is the British heavyweight Anthony Joshua.

The 27-year-old might be younger than both McGregor and Mayweather, but he’s dispensed some very shrewd advice to the superstar duo about how to behave once the fight is over.

Listen up, Conor and Floyd…

“No matter the outcome, they should show a lot of respect and class,” Joshua was quoted as saying by the Mirror.

“Sometimes what you say after, if they can show a bit of class and integrity, will capture the attention of adults who will tell their kids, ‘listen to what they said.’

“It gives kids a window to come into the sport, then you’re creating more champions, it keeps people in jobs for longer. People always remember the end.

“People will look at the Mayweather versus McGregor fight and then they’ll start filtering down, everybody will benefit.”

Very well said, Anthony.

Can McGregor and Mayweather act responsibly this weekend?

Unfortunately the four recent press conferences involving Mayweather and McGregor were marred by a series of unsavoury and ill-advised comments.

They were both trying to sell the fight, of course, but lines were overstepped this summer.

The next generation of potential boxers and boxing fans will be looking up to Mayweather and McGregor this weekend - and hopefully they manage to act responsibly once the fight is over.
