It must have been a huge relief for Lewis Hamilton when he finally secured his fifth Formula 1 title at the Mexico Grand Prix last weekend.
The Mercedes star could have sewn it up in the United States after winning in Japan, but he was made to wait, thanks to Kimi Raikkonen.
Hamilton got the job done at the second time of asking at the Autodromo Hermanos Rodriguez, though, adding to his 2008, 2014, 2015 and 2017 championships.
Now more than ever, fans are wondering if the 33-year-old could genuinely be considered the greatest F1 driver of all-time.
Even though Hamilton is only two titles behind Michael Schumacher, Alain Prost feels it’s a question that will never be answered.
“You cannot compare the generations," the four-time champion told Sky Sports F1, via f1i.com.
"Senna and I were perhaps the best of ours.
"Now you can only say that Lewis is one of the best, if not the best of his generation.”
Hamilton deserves huge credit for sustaining such a high level of consistency over the past five or so years, but Prost believes something sets him apart.
“Multiple world champions are obviously doing something different from the others,” he said.
“The biggest difference I notice about Lewis is how he forces himself to become an even better driver.
“This was perhaps his best season and he can be even better.
“Sebastian also had a good season, but not good enough to beat the combination of Lewis and Mercedes.
"Even if his car is not that good, he takes second or third place… And if he has to do something special in qualifying he is able to, like in Singapore.”
WHY HAMILTON WAS UNSTOPPABLE
But why was Hamilton so difficult to reel in this season?
Well, despite claiming he was “impossible to beat”, Prost says the origins of his dominance are relatively simple.
“Lewis was psychologically very strong against Seb this year," he said.
"He was very mature and under the circumstances, he was impossible to beat.
"[Sebastian] made mistakes at the wrong time, as in Baku or Hockenheim, otherwise he would have been 30 points ahead at the time and with less pressure.”
Additionally, Mercedes clearly has a huge impact, particularly relating to their willingness to let Hamilton pursue his interests outside of racing - something that often draws criticism.
“[The team] supports Lewis in his special way of life, which gives him a lot of confidence and strength - which is very important to him,” Prost said.
It really is difficult to find even a minor fault with the state of affairs at Mercedes right now.
