Mercedes still hoping for more in 2010

Michael Schumacher and Nico Rosberg delivered a fourth and fifth-placed finishes for Mercedes GP in Istanbul, as the outfit led the chasing pack behind Red Bull Racing and McLaren.

But despite having edged clear of Ferrari in Turkey, and the longer wheelbase upgrade package having helped deliver a better car, Haug says the team is still hungry to improve.

"I would hope for more," Haug told AUTOSPORT. "We want to be a winning team, but we need to be patient and we need to keep working hard.

"The car is very reliable, all the ingredients are there, and regularly we do the best pit-stops. We need to just realise that and close the gap to the front.

"Ferrari is a question mark as we don't know if they could have been faster, and they certainly did not have a very strong weekend, but it is still not good enough. Having said that, we were good as a team, we are composed, concentrated, but we need a lot more speed."

Haug has said that despite Mercedes GP not winning the race, he still took satisfaction from McLaren's 1-2 finish.

"All in all we need to improve our speed and we are working on that, but generally speaking it is fine for us if McLaren wins," he said. "If we cannot win, it is good. And I think even if the Red Bulls would not have crashed the race was not over.

"It was the 71st victory for us since 1997, which is quite a number, and I think that statistically it is every fourth race that we have won."
