2016 F1 World Champion says that Max Verstappen is on a level of Lewis Hamilton, Michael Schumacher and Ayrton Senna.
Verstappen is in his way to winning his 3rd straight World Title. Only Hamilton, Schumacher, Sebastian Vettel and Juan Manuel Fangio have ever done that.
Speaking to Sky Sports, Rosberg said: “We are witnessing real historic greatness in line with Schumacher, Hamilton, Senna.
“It’s a really incredible performance, extraordinary.”
“That talk from him [possibly retiring] started in the year when he battled Hamilton, where he said ‘I won’t go on for very long if every year is like that’,” explained Rosberg.
“Those battles are so fierce and intense, it takes a lot of the fun away as well.
“The sport will always be an intense environment, especially when you are fighting for championships every year and you are the guy who has it all to lose. Every expectation is you are going to win over and over, it’s quite demanding.
“I can’t put myself in his shoes. Money-wise, he’s done. He has so much he won’t have to work again or worry again. Record-wise he’s already one of the best of all time by the end of this year.”
