Team Sky boss Dave Brailsford said Chris Froome is "right up there with the greats" and sees no reason why he cannot add to his tally of four Tour de France titles.
Froome continued his dominance of the Tour by sealing a third consecutive triumph on the Champs-Elysees on Sunday.
The Brit failed to win a stage on the 2017 edition, but was only without the yellow jersey for two days once he took over from team-mate Geraint Thomas at the end of stage five.
Jacques Anquetil, Eddy Merckx, Bernard Hinault and Miguel Indurain are the only riders to have won the most prestigious Grand Tour race more times - that esteemed quartet all having triumphed on five occasions.
Brailsford thinks Froome, who will be 33 when next year's race gets under way, can join or surpass them if he retains the desire which has brought him so much success already.
"Chris can go on - there's no reason to think that he can't," Brailsford told ITV4. "Physically he's got what it takes and I don't think that's going to diminish in the next year or so.
"He's getting better tactically and technically, so as long as that hunger continues and he keeps his health, then he'll be a force in this race for a good couple of seasons to come."
Froome has failed to win the hearts of the majority of the French public, but that is of no concern for Brailsford.
"I don't think it's a popularity contest," said the Team Sky team principal.
"You've got to look at the sporting achievement and Chris is right up there with the greats now, there is no denying it. He'll be thinking about the respect amongst his peers in terms of what he's achieved and how he's achieved it and he's got the utmost respect from them.
"He deserves all the accolades he gets and I'm proud of Chris Froome - he's a great ambassador for the sport and a great ambassador for Team Sky and I'm sure a lot of people think the same."
