KSI and Logan Paul are now days away from their highly-anticipated rematch.

The two internet sensations, who boast a staggering 40 million subscribers between them on YouTube alone, go head-to-head at the Staples Centre in Los Angeles on Saturday night.

The first fight between the two social media celebrities, which took place at the Manchester Arena in August 2018, ended in a majority draw. But unlike that fight, their upcoming bout is a professional boxing match.

The headguards are off this time around and we’ll see them slog it out for six three-minute rounds.

Both fighters are supremely confident of victory, although Logan Paul is currently the firm favourite with the bookmakers

The American, who is being trained by Shannon Briggs, looks is fantastic shape and told reporters earlier this week that he will become heavyweight champion of the world if he decides to become a boxer.

KSI is priced at around 13/8 with the bookies to win this weekend’s rematch; however, those odds might shorten slightly after footage of the 26-year-old looking surprisingly quick on the pads emerged.

Impressive stuff from KSI, whose real name is "JJ" Olatunji.

Some boxing fans were convinced the footage must have been sped up to make KSI look better.

But the guy who posted the clip - @jezzyminter - followed it up with another angle proving nothing had been edited.

Lots of people were genuinely surprised to see how fast the YouTuber looks…

Of course, doing it on the pads in training and doing it inside the ring on fight night are two very different things.

There are no guarantees that KSI will be able to replicate this hand-speed when faced up against Logan Paul.

KSI, though, also made headlines last week after knocking out his sparring partner in training.

"I'm obsessed with boxing, I couldn't say that two or three years ago, but now I've got such a hunger for the sport," KSI told Sky Sports this week.

"I plan on doing more fights, why would I stop, I'm in the best shape of my life. It works well with what I've got in mind.

"I don't ever think I'll become a world champion, but I can definitely fight other pro boxers and beat them. I'll take opportunities that make sense before I get to the point where I decide to hang the gloves up.

"I have hidden power and now, without headguards, I will go in there and knock [Logan Paul] out. I haven't knocked someone out properly before, I have in sparring, but not in front of the world."
