David Beckham's youngest son has hit back at Cristiano Ronaldo for claiming he is physically superior to the retired Manchester United ace. 

Ronaldo was drawn on who he thought was the better looking during a recent sit down interview with Piers Morgan Uncensored. 

Somewhat predictably, the Portuguese striker, 40 - now into his third season with Saudi Arabian side Al Nassr - was unequivocal in his response. 

'His face is beautiful, yeah, handsome face,' he said. 'The rest is normal, like it's normal. I'm not normal. I'm perfecto.'

Taking to Instagram on Monday, Cruz Beckham, 20, referenced the comment by comparing Ronaldo's facial features shortly after he signed for Manchester United as a relatively unknown teenager in 2003, to those of Beckham when he was in his early twenties. 

The record breaking striker was a rough-around-the edges 18-years old when he joined the Premier League giants following one impressive season with Sporting Lisbon, and Cruz appeared keen to draw attention to his less than polished appearance while matching the photo alongside a rather more flattering image of his father. 

'For me [good] looking is not only the face but the whole package,' a bullish Ronaldo explained during his November interview with Morgan. 

'Imagine Cristiano and a normal guy with red speedos on the Copacabana, you think I am not going to have a chance with nobody.'

Pressed again on the comparison to Beckham, Morgan eventually drew a boastful answer from the legendary footballer.

'You're walking across the Copacabana for, say, ten minutes. Who gets the most attention?' he asked.

'Me, 100 percent,' Ronaldo boasted, prompting laughter from Morgan.

The light-hearted comment drew laughter from the pair, before Ronaldo offered a more charitable opinion about the former Manchester United and England ace. 

'He's looking good,' Ronaldo admitted. 'I like him, he is a guy who speaks good, I like him.'

The Portuguese star - the world's first billionaire footballer - also suggested he is the most famous person on the planet, saying: 'We'll do a debate for the world, who's the most famous? Me or President Donald Trump? 

'I think, in the world, even in small islands, they know me more than him.'

Meanwhile, Cruz has pushed back against claims that he plagiarised The Beatles and Oasis as he steps into the music industry.

The musician recently released the double A-side single Optics and Lick The Toad. 

Additionally, he has been performing a series of small live shows across London with his band. 

On Sunday, he responded to several comments on social media suggesting his tracks sound too similar to the legendary bands.

Posting a screenshot of the remarks to Instagram, he wrote: 'Yeah u mean like... writing a song. 

'Some people hurt my brain. Jealousy ignites delusion. Bl**dy hell.'
