The F1 circus is a long time away but, for the time being, Vettel does not seem intent on returning to the track. The four-time World Champion (2010, 2011, 2012 and 2013) is enjoying his new life, even if, from time to time, he returns to talk about Formula 1, which is the world he knows best and in which he experienced the most exciting moments of his career.

The former driver of, among others, Red Bull and Ferrari, revealed who he thinks are the best in the history of Formula 1: "I would say the best are Michael (Schumacher) and Lewis (Hamilton). Whyé? Becauseé the numbers speak for themselves. Michael was my hero and Lewis has the best stats", his words reported by Marca.

Then Vettel explained who, in his opinion, è was the toughest opponent he has had to face in so many years of his career: "Fernando (Alonso). I had many duels with him and throughout my career, in general, è always been the, ready. È; very competitive. Sì, I think he has been the&39;toughest opponent I have ever faced".

Alonso who, unlike Vettel, è still on track. Despite being six years older than Vettel, the Asturian has not lost his desire to compete. Could this be a spur for Vettel to return to the track as well? At the moment, it really seems that the German driver has other plans, definitely outside the world of F1.
