Jun.12 (GMM) Sebastien Bourdais has proved he deserves his place on the formula one grid.

That is the opinion not just of his Toro Rosso chiefs, but also Williams co-owner Patrick Head, who is expecting to see increasingly impressive performances from the Frenchman.

"Like a lot of things, you've got to get everything working together," Head is quoted as saying by AP, noting that - until Monaco - Faenza based STR was using an old car.

Head added: "I think he well justifies his place in formula one and I quite expect to see him starting putting results together soon."

Bourdais, 29, struggled for years to earn a place in formula one, despite his immensely impressive career in American open wheelers.

He is therefore accustomed to winning, but insists that he is nonetheless enjoying his new career at the pinnacle of European racing.

"If the car is only good enough for 15th and you finish 12th, sometimes it's even more satisfying than just winning the race with a car that everybody knows is capable of winning," he said.
