Germany's new Formula One star Sebastian Vettel insists comparisons with seven-times world champion Michael Schumacher are far too premature, in a frank interview set to appear here Sunday.

Vettel, 21, was the first German to win a Grand Prix since Schumacher's final success in Shanghai two years ago when he won his 91st title in his 250th race before retiring.

Last Sunday in Monza, Vettel claimed his maiden Formula One victory at the Italian Grand Prix and became the youngest race winner, 24 hours after becoming the youngest man to take pole for a Formula One race.

But in an interview set to appear here in Die Welt on Sunday, Vettel says each of the numerous articles he has read comparing him to Schumacher is wide of the mark.

"Each comparison is somewhat presumptuous," he said.

"You can't copy anyone.

"Everyone must go his own way and I am no different.

"If you try to be like someone else, it doesn't work, no matter how hard you try.

"And I think each driver who achieves only a quarter of the success Michael accomplished will already be extremely successful.

"You have to keep your feet on the ground and put things in perspective.

"Michael won seven world titles — that is pretty hard to understand from the outside.

"But when you drive week in, week out, for a whole Formula One season, you have a much better idea of the level Michael drove at and for how long.

"Michael is one of the best drivers who has ever raced.

"Even me being compared to the likes of Fernando Alonso or Kimi Raikkonen would already be too much."

With four Grand Prix races left, Vettel is ninth in the drivers' world championship table behind leader Lewis Hamilton before the next race in Singapore on 28 September.
