Murray Walker has said that he expects Sebastian Vettel to win eight Formula 1 world championships during his career.
The 25-year-old German has won the drivers' title for the last three years.
The former commentator told Metro: "He is very likely to beat [Michael] Schumacher's record [of seven titles].
"If he doesn't beat the record it will mean he hasn't made very good choices about the car he drives. But he is a very astute bloke and I don't think he will make bad choices."
Vettel's success in the last three years has also guided Red Bull to three constructors' championships.
