Ronaldo and Messi have been breaking football records for the best part of a decade, but who would have the edge in the boxing ring? Anthony Joshua has had his say...
The world heavyweight champion told Youtube channel 'COPA90': 'Messi's got that ruggedness but Ronaldo looks like he's got the Bruce Lee - bang!
'You know what I mean, just stand there and lick you with one hook and you're finished. Messi seems a bit more like his name... messy and rugged.'
Joshua also spoke of his admiration for Ronaldo, saying, 'I've been pro now for three years, and I think early on I was trying to do everything because with boxing I come into the game as a professional.'
'Remember I haven't had much background, so I had to present myself to the world - so for the first three years I was managing, managing, marketing and marketing.
'But now I'm at a stage where I've just said I've done that, now I want to focus on being the best boxer then I get the inspiration from Ronaldo.
'It's just little things. He would train by himself afterwards to work on what he wanted to work on.
'I was speaking to [Ronaldo's former Manchester United team-mate Rio] Ferdinand who said he was the only one in the team back then who had masseuses, nutritionists, psychologists, so he had that desire.'
