Manchester United have been offered hope of re-signing a fully firing Cristiano Ronaldo, after Portugal's national team physio suggested the Real Madrid superstar can stay at the top of the world game until 2020, reports the Daily Star.
The 28-year-old forward recently quashed speculation surrounding his future by penning a new long-term contract at the Santiago Bernabeu, that will keep him in the Spanish capital until 2018.
Ronaldo had been heavily linked with a return to the Premier League champions, after hinting that he would like to finish his career at Old Trafford.
Red Devils boss David Moyes thought that any hopes of bringing the Real Madrid star back to England had diminished, after Ronaldo signed a deal that will see him stay in La Liga until aged 33.
However, according to Portuguese physic Antonio Gaspar, Ronaldo has the physical fitness to be at the peak of his powers until aged 35, which could pave way for a move back to Manchester United at the end of his new Real Madrid contract.
"I think an athlete like him can easily carry on until 33," explained the Portuguese physio, who knows Ronaldo's body like the back of his hand. "In fact, in his case, I reckon that, barring anything untoward, he will be at the peak of his powers even longer, until 35.
"He's a super-athlete, way above the average in that sense, and he's also a top professional who takes perfect care of himself and doesn't miss a trick when it comes to his diet and recovery time.
"Real Madrid know what they are doing, it's not a gamble, and Ronaldo will be at the top of his game until the end of his contract."
