Dennis rebuffs Kubica's Hamilton criticism

Kubica told the German media at the Japanese GP that he felt some of Hamilton's driving standards this year had been questionable - especially his hard tactics at the Italian Grand Prix.

And after Hamilton himself brushed aside Kubica's remarks, his team boss is now also adamant that Kubica's comments are misplaced.

"I think he should focus on his own driving, and leave it to those people who have as a part of their responsibility to determine how good, bad or indifferent another driver's performance is," said Dennis.

"There's obviously regular team processes in the respect of the application of the stewards, but from a team perspective, and that's the only perspective that I can talk from, I share the view that's held by probably everyone up and down the pitlane.

"It's refreshing to have a highly-talented driver who has the ability to overtake and has the ability to do the pole positions that he's done in what is only his second season of Formula One.

"So I think he (Kubica) should be mindful of the fact that his objective should be to raise his own game and do the best job he can, and keep those sorts of opinions to himself."

Mercedes-Benz motorsport boss Norbert Haug has said he is not surprised by Kubica's remarks, and thinks it to be expected that the opposition choose to take swipes at Hamilton.

"For me it's normal. What do you expect? Nobody likes to be overtaken and I do not expect the opposition to hail Lewis. That is quite normal. They can say what they want and I have my opinion and I'm not speaking about other drivers.

"But I think on the occasion of a very important pole position it's for me not the right timing to discuss the opinions of other drivers."
