FILIPINO boxing legend Nonito Donaire was a surprise padman for YouTuber KSI, who is preparing to rematch Logan Paul.
The internet sensation rematches his rival on November 9 at the Staples Center in Los Angeles.
After they fought to a draw in an exhibition bout last year, the social media rivals have now sensationally turned professional for the second mega-money bout.
And Brit KSI – real name Olajide William Olatunji – was seeking pro advice in Las Vegas at the City Athletic Boxing gym.
The Mayweather Boxing Club shared footage of former four-weight world champion Donaire giving the YouTuber some tips in the ring.
KSI revealed the 36-year-old – who lost to Carl Frampton last year – helped improve his “boxing IQ” during the pads session.
He said: “He just came through and told me some gems.
“This is why I love coming to places like this, there’s nothing like it.
“You have world champions coming through and telling you to do this, do that. It just increases your boxing IQ and makes you a better boxer.
