Dimitar Berbatov has mentioned Neymar, Kylian Mbappe and Mason Greenwood as the players who could potentially emulate Cristiano Ronaldo and Lionel Messi in the future.
The duo, who have shared 11 Ballon d'Or awards between them and are widely considered two of the greatest players to have ever played the game, are both now in their 30s and may not be far off the end of their respective careers.
Paris Saint-Germain duo Mbappe and Neymar have long been touted as having the potential to be world football's two biggest stars when Ronaldo and Messi decide to call it quits, with both having arrived at the French club for enormous transfer fees.
And Berbatov also mentioned Greenwood, who has burst onto the scene at Manchester United and been one of the club's best players since the Premier League restart, as being another who could one day reach the very highest level.
When asked about his former team-mate at Old Trafford, Berbatov told Betfair: "On Friday, it will be two years since my former team-mate, Cristiano Ronaldo signed for Juventus.
"No one can say Cristiano hasn't been amazing in Italy, especially considering his age. He's 35 now, oh my God, most players have dropped a level by now, what he's still doing is unbelievable.
"He takes care of himself very well, probably better than he ever has, because at that age you need to work harder to stay in good shape. Messi and Ronaldo, we need to treasure them, because when it's over, it's over. They have been more than special.
