Massa: Ferrari stronger than it looks

The four-day test ahead of this weekend's Italian Grand Prix was dominated by rivals McLaren, with their drivers topping the times in all sessions.

However, Massa reckons Ferrari are in much better shape than it seemed following their dominant one-two at the Turkish Grand Prix.

"We are a lot stronger than it looks, that's for sure. We can fight with McLaren, we'll see if we'll be able to be quicker than them," the Brazilian told Autosprint.

"I think it'll be a two-way fight, as it's been so far. Maybe in the race some others managed to get in the fight, but not in qualifying.

"We've almost always had the same amount of fuel and the difference in laptimes were insignificant.

"In testing I've often lacked the conditions to run at my best, but we set out best laptimes at the beginning of the runs, with a lot of fuel, while they set theirs at the end of the runs."

Massa confirmed Ferrari will keep on pushing with the development of their F2007 car for the last three races of the year, and the Italian squad will introduce several new components in order to try and beat McLaren.

"Yes, that's correct," Massa added.

Massa is 15 points behind championship leader Lewis Hamilton with five races to go.
