Red Bull team principle Christian Horner says the battle between Lewis Hamilton and the "wave" of emerging talent including Max Verstappen and Charles Leclerc will be "fantastic" for Formula 1.
While Red Bull's Verstappen and Ferrari driver Leclerc, both 22, were powerless to stop Hamilton from securing his sixth F1 world championship, they both impressed and during the winter have earned new long-term deals with their respective teams.
Leclerc has committed to Ferrari until the end of 2024, while Verstappen is due to remain at Red Bull until a year earlier.
Though Hamilton's Mercedes team has dominated F1's hybrid era, Horner is convinced F1 is due for a "classic" between its three biggest teams this year due to regulation continuity, before things are shaken up by the 2021 rules revamp.
"Every now and again, you get a wave coming along and I think we've got that at the moment," Horner said.
"So I think especially exciting is the Max/Leclerc dynamic, how that's going to play out over future years, how Lewis can still go toe to toe with those guys.
"Because there's life in him yet as well and I think he's keen to gauge himself against the young wave that's coming through.
"I think for Formula 1 it's fantastic to have the dynamics of the young guys, the challengers, coming through and some of the older guys that are the old dogs that know all the tricks."
Hamilton, who is out of contract at the end of 2020, is widely expected to commit to a new Mercedes deal, especially after Verstappen's and Leclerc's long-term agreements.
The 35-year-old has repeatedly made it clear in 2019 that he does not plan to retire soon.
"The core of what I do is that I love racing, I love the challenge," Hamilton said.
"I love arriving knowing I have got these incredibly talented youngsters who are trying to beat me and outperform me, outsmart me, and I love that battle that I get into that every single year.
"And I am working with these guys who are so much smarter than me and they make me feel smarter, [and] when I am challenging them and proving them wrong so many times, it is unreal!
"I don't fear [the day I retire]. It is going to be a sad day, to hang up and stop doing something you've loved your whole life and as long as you can remember.
"But that is why I have all these other things in place that I can fall back on.
"The fashion side, for example, I've found another business that I can do for a long time if successful.
"Currently that is going really, really well but I don't know how long it will go. But at least I have another interest."
