McLaren unconcerned by intra-team rivalry

And team boss Ron Dennis has made it clear that all McLaren are thinking about is beating their opposition.

"The competition is those cars in front of us," said Dennis, whose team took their first victory for more than a year in Malaysia last weekend.

"We don't worry about each other. We just concentrate on beating anybody that sits in front of us on the grid or on the race circuit."

Mercedes motorsport boss Norbert Haug has also urged onlookers not to get too excited with Hamilton's form in his first two races - and remember that the Briton is going up against one of the best drivers in the world.

"We should not get carried away with his second race," said Haug. "He is doing a fantastic job and he knows he is driving against the most complete racing driver in F1.

"I think it is a great achievement so far what he has done. But we will do it step by step, and of course we will push the car further.

"I think it is remarkable if a guy like Fernando still says we can improve the car and improve himself. This is team play and I think it is very, very positive for us."
