Ronaldo hit yet another breathtaking milestone of an extraordinary career when he netted his 500th professional career goal in Madrid's 2-0 Champions League victory over Swedish side Malmo on Wednesday night.
The superstar has also drawn level with Spain legend Raul as the La Liga giants' all-time record goalscorer with 323 goals in all competitions after doubling his tally later in the match.
And the Portuguese star's headline grabbing performances have once again reignited talk of a possible return to England with the Red Devils – as reported by the likes of the Manchester Evening News – where he enjoyed spectacular success as a player under Sir Alex Ferguson.
'I'd love it but I can't see it'
But speaking to talkSPORT, another Old Trafford great, Beckham, says fans should not get their hopes up over a return.
"That would be great because he was so great at Man United.
"But he is at Real Madrid now, he is very comfortable in his life there, the fans obviously love him there, and he looks a real Real Madrid player now."
Red Devils still a work in progress
There was an air of resignation in Beckham's voice as he delivered his verdict.
And aside from the obvious advantages of living in the Spanish capital over Manchester, the ex-England captain makes a salient point.
Had United been at a different stage of their development under Louis van Gaal, they may have been a more realistic proposition for Ronaldo.
But the truth is they are still a work in progress, despite being one of the early frontrunners in the Premier League this season.
They are in the middle of a major rebuild under the experienced Dutchman after the David Moyes debacle and while Ronaldo's return would undoubtedly speed up their development, he is unlikely to risk personal glory in the latter years of his career.
Realistically, Madrid are serious contenders for all major honours, including the Champions League, and United, for now at least, are not.
