Sebastian Vettel has said that he may quit Formula one in five years.
Vettel has been a dominant force in F1 in recent years, winning the last three drivers championships, and he is well in position to make it four.
He is currently 21 points clear of Kimi Raikkonen who is in second.
His season so far has not gone without controversy, with a very public spat with Mark Webber ongoing. Webber will quit Red Bull at the end of the season because of Vettel, and when questioned on his own future, the 25-year-old admitted he may not be in the sport in five years.
“I can’t say [about my long-term future at Red Bull]. Perhaps I will no longer be driving in five years’ time because I no longer have the urge to,” he told German newspaper Welt Am.
“Perhaps I will compete for another team in five years because I feel ready for a fresh challenge. Every human being evolves as time goes by, priorities shift.
“Right now I feel completely at ease here and I could not imagine driving anywhere else.
“The car is quick, the team does well – I see no reason to leave. But that does not automatically mean I will stay forever.”
Vettel has a contract until the end of next season, and has been linked with a move to Ferrari.
