Former champions urge Hamilton to keep his cool

LONDON: Britons Jackie Stewart and Damon Hill have told compatriot Lewis Hamilton he must keep his cool in the season's last two races if he is to join them as a Formula One champion.

The 23-year-old McLaren driver leads Ferrari's Brazilian Felipe Massa by five points and could become the sport's youngest champion if circumstances favour him in China this weekend.

However Hamilton failed to score in Japan on Sunday, reviving fears that history may be repeating itself after he allowed a commanding lead to slip through his fingers at the same stage last year.
