Sebastian Vettel should rethink his policy of not employing a manager, according to former triple world champion Sir Jackie Stewart.

21-year-old German Vettel, the only driver other than Jenson Button to have won a race this season, negotiated his BMW, Toro Rosso and Red Bull assignments with the assistance only of his father Norbert, and an external lawyer.

"Up until now he didn't need a manager," Scot Stewart, 69, told Germany's Auto Motor und Sport.

"But he will not be able to imagine what is going to happen to him if he really becomes a superstar," Stewart added.

Stewart, also a team owner and boss at the end of the 90s, believes Red Bull driver Vettel has not reached his peak of popularity, which will complicate the handling of his own affairs.

"He will become so big that he needs someone to guide him through the things that, apart from driving, are important," he continued.

"He will be dealing with people like politicians, heads of big companies. He should be prepared for that," added Stewart.
