Johnny Herbert is not very impressed by his former team-mate Heinz-Harald Frentzen. Herbert said: "He is not very strong psychologically."

He added: "When we were together (at Sauber) people tended to say to him: better next time. I don't think he can expect the same at Williams-Renault. Nowadays you have to mentally strong. Heinz-Harald has to show more perseverance."

Gerhard Berger's wife Ana has given birth to a baby girl named Heidi today. Berger said: "This joy is incomparable."
