Despite all the rumour and speculation lately concerning a much-discussed fight between Conor McGregor and Floyd Mayweather, it is fair to say there are a lot of people who firmly believe the two will never face each other in the ring.
While that may yet prove to be the case, one man who doesn't appear to be taking any chances is the UFC superstar himself.
That's after footage emerged today showing McGregor working on his boxing technique during a sparring session with former IBO welterweight champ Chris van Heerden. Scroll down this article to check out The Notorious One's skill set for yourself...

While it certainly looks like McGregor is putting in the hard work to put himself in the best possible position should the "mega-fight" with Mayweather come to fruition, on the evidence of this video it looks like the 27-year-old MMA fighter has some way to go before he could even contemplate stepping foot inside the ring with the 49-0 boxing great.
Chris Van Heerden is an adept fighter himself, mind, having amassed a 24-2-1 record in over a decade as a pro, so McGregor isn't exactly starting off easy when it comes to improving his boxing ability.
The L.A. gym's owner Tony Jeffries, who told TMZ that McGregor has been coming in to train every day since last Friday, actually believes the UFC star may have a chance versus Mayweather having watched him work over the past few days:
"I never thought [Conor] had a chance at beating Floyd until I saw him box today. Now I am on the fence," he said.
Coming on the back of Mayweather's recent claims that a McGregor fight will "absolutely" happen, today's footage will only ramp up expectation.
However, there are those who believe McGregor's recent interest in boxing is actually related to his future plans inside the UFC octagon.
As noted by some, Van Heerden's physique is much more akin to that of Nate Diaz, the man who handed McGregor his first ever UFC defeat earlier this year.
With a rematch still expected to happen at some point in the not too distant future, the Dublin native may simply be looking to improve his stand up game as he seeks revenge against his rival.
