Cristiano Ronaldos Elite Fitness Mindset Helped Extend Career Beyond 40

Clegg said Ronaldo’s focus on recovery, diet, sleep, and injury prevention explains why he is still playing at 41.

As the football world prepares for another FIFA World Cup, former Manchester United fitness coach Mick Clegg has explained why Cristiano Ronaldo is still competing at the highest level, even at 41. Clegg, who worked closely with Ronaldo after his £12.24 million move from Sporting CP to Manchester United F.C. in 2003, described the Portuguese star as the best trainer he had ever coached.

According to Clegg, Ronaldo stood out from the very beginning because of his obsession with improvement. Even as an 18-year-old, he was already focused on areas that many players ignored at the time, including sleep, diet, recovery, injury prevention, and strength work. Clegg said this early discipline helped Ronaldo build habits that have extended his career across clubs like Real Madrid CF and now Al Nassr FC. One story highlighted Ronaldo’s mindset perfectly.

After arriving at United, he reportedly asked about everything club legend Ryan Giggs did in the gym because Giggs was known as the hardest worker there. Ronaldo’s response was simple: he wanted to copy it all and do it even better. Clegg also compared Ronaldo with Wayne Rooney, calling Rooney a natural footballer, while Ronaldo was obsessed with becoming the absolute best through relentless physical and mental preparation.
