Manchester United players laughed at Cristiano Ronaldo’s aspirations when he arrived at the club in 2003.
But it is revealed by Fletcher that many United stars would tease him for his obsession with being the very best.
“He had a mindset that he was going to be the best player in the world from the day when he came into the club,” he told Sky Sports.
“He took training to another level.
“At first, people loved the desire but he did get stick for it with people saying: ‘It’s easier said than done.’

“The lads were laughing at him but he didn’t care and it didn’t deter him. Ultimately people respected it.
“The lads saw it as a bit of banter but deep down they respect that work rate.
