Ferrari Duo Unhappy despite Top Ten

Schumacher took seventh place on the grid with Barrichello just three places back - although both felt they could have done much better.

"I am not happy with my lap this afternoon," said Schumacher. "It started well, but towards the middle section I began to lose grip and I think this was because the tyre pressures went up higher than we wanted, causing me to slide around.

"But, looking at the data, it seems it was not just down to the pressures, so the track must have been more slippery than in the morning, which can be seen from looking at the other drivers' times.

"When I saw my lap time, I expected to be much further back on the grid, so this is not such a bad result at the end of the day."

Barrichello, who has been on pole position for the last two Brazilian Grands Prix, added: "I am very disappointed because this morning the car was set up very well.

"But this afternoon, the car was bottoming pretty much all the time and because of this I lost about 5 km/h going down the straight and it was even difficult to steer. Now, the engineers are checking what was the problem.

"I am really disappointed, because I think I could have done around a 1'12"1 which would have put me on the first or second row."
