Warwick has no faith in David Coulthard.

Ex-F1 driver Derek Warwick has said that although he would like to see David Coulthard win this year's World Championship he doesn't think the Scot has what it takes.

He told British newspaper The Sunday Mirror: "It was a stunning drive by David at Interlagos, especially in those wet conditions. It was the drive of a potential world champion. But unfortunately he hasn't been able to produce enough of those drives in a season to give himself a chance of winning the championship."

"I want him to do it, and my heart says he can - but my head tells me he can't. I just don't see it. I think he's a good number two. At another team he'd be good enough to be number one, but not at McLaren."

The veteran of 147 GPs added: "(Michael) Schumacher's the best driver in the world, (Mika) Hakkinen is second, and he still has chinks in his armour. Then you're looking at the rest - and David is one of the rest. I think it will be Hakkinen taking on Schumacher again at the end."

"David seems to have a switch inside him and when it's on he can be as good as Hakkinen. But he's not yet been able to keep it on for 17 races a year. Normally it's for four or five races."

"In order to be a great racing driver - like Schumacher, like Hakkinen, like (Nigel) Mansell, like (Ayrton) Senna, like (Alain) Prost and all the great champions you can name - you have to do it lap after lap, race after race. They've got the drive and the motivation to keep doing it. That's what makes them different from the rest. I'd love to see David put together those races over a season and win the title. It would be great to have another British champion. But I honestly don't think he will do it."
