Wayne Rooney has had his say on Real Madrid forward Cristiano Ronaldo, discussing the Portuguese star in his new book 'My Decade in the Premier League', which has been serialised by the Daily Mirror.
The 26-year-old tells tales of how his former Manchester United team-mate can't even walk past a mirror in the Old Trafford changing room without checking himself out, and praised Ronaldo's burning desire and determination which makes him one of the best footballers on the planet.
"In the time I've been playing with Ronnie, the one thing I've noticed about him is that he can't walk past his reflection without admiring it, even if we're about to play a game of football," recalled Rooney.
"Every match, before the team goes out for the warm-up, he runs through the same routine. The kit goes on, the boots go on. Not long after, Ronnie turns to his reflection and stares, psyching himself up for the game.
"If there's one person with a bigger self-belief than Ronaldo then I haven't met him yet. He's not shy.
"He loves his clothes and the clobber he wears is always super-expensive and covered in shiny logos – Dolce & Gabbana, Armani, you name it, he's swaggered into the training ground wearing it, looking immaculate from head to foot.
"He must spend a fortune on his wardrobe. But Ronaldo's biggest love is football."
After six successful years in Manchester, Ronaldo was sold to Real Madrid in a club record £80million deal, where he has scored 150 goals in 149 appearances, helping Los Blancos to La Liga title last season.
However, the Portugal captain sent shockwaves through football at the weekend when he revealed he was unhappy at the Santiago Bernabeu, leading to rumours that he may be preparing to leave the Spanish capital.
Ronaldo's drive to be the world's best has been somewhat eclipsed by the excellence of Lionel Messi at Barcelona over the past three years. And, whilst his hunger and passion for personal success has drawn a number of detractors over time, Rooney suggests that they're personality traits the forward has possessed for years.
"At the training ground he [used to] tell us he wants to be the best player in the world, that he's desperate to be the greatest," he continued. "He has the determination about him to make it happen, too.
"Fair play to him, I like that attitude, but it's not for me. I'm more into helping the team to win things rather than getting any personal accolades or special gongs for the mantelpiece at home.
"But if Ronnie wants to be the best footy player on the planet and it helps United to our first Premier League title since I've been here, well, I'm all for it."
