Lewis Hamilton can bounce back from a difficult three years to win a record-breaking eighth Formula One drivers' championship, eclipsing Michael Schumacher's achievements.
That is the view of 1978 champion Mario Andretti, who does not believe Hamilton has made a mistake by committing his future to Mercedes.
Hamilton equalled Schumacher's record haul of seven world titles in 2020, but he has failed to surpass the German great amid three years of dominance from Max Verstappen.
Having edged out Hamilton for the 2021 title in controversial circumstances, Verstappen has dominated the last two seasons while his rival has struggled.
Verstappen clinched his third straight title with six races to spare by finishing second in the sprint race in Qatar last Saturday, and the Dutchman followed that up with another triumph on Sunday – his 14th victory in 17 Grands Prix this year.
While Verstappen holds an unassailable lead over Red Bull team-mate Sergio Perez in the drivers' standings, Hamilton has found himself battling Fernando Alonso for a top-three finish, having ranked sixth last year.
Despite rumours linking him with Ferrari, Hamilton extended his contract with Mercedes until 2025 in August, and Andretti believes the 38-year-old made the correct decision.
Asked if Hamilton needed to move to boost his chances of winning another title, Andretti told Stats Perform: "Why would he go anywhere else?
"With Mercedes, that is probably the best possibility to resume his winning ways and win another title. No question. He's young enough.
"He certainly still has the desire to be at the top. After being a multi-time world champion, you don't lose that ability.
"Right now, he equalled a record that I thought would never be approached, not in my lifetime anyway. He's still young enough that he could go for the eighth title.
"It's going to take a long time for anyone to reach that and surpass that. So yeah, he's definitely one of the greats, for sure, deservedly so."
Hamilton sits 11 points clear of old rival Alonso in the standings ahead of next week's United States Grand Prix, with the Spaniard enjoying a resurgence since leaving Alpine for Aston Martin ahead of the 2023 season.
Having won four IndyCar championships during his own career, Andretti has a particular admiration for Alonso, who himself competed in the IndyCar Series during a two-year stint out of F1.
"Oh, Fernando is timeless," Andretti said. "I just love to see how much energy he still has and how much desire is still within him.
"After taking a sabbatical from Formula One, I thought, 'I don't know, he'd better be careful about coming back'. Here he is, coming back as strong as ever.
"I think he brought Aston Martin to a level that they almost did not expect. They certainly are giving him equipment which is capable, but he's taking it there.
"Fernando's legacy is that of a very ambitious driver, to try to conquer different disciplines. He ventured into IndyCar at Indianapolis. I respect somebody like that.
"That's pure love for driving and the sport, to be curious like that, not just to drive, but to try to win in a category that's not your speciality."
