Fernando Alonso has no idea how his Ferrari will compare with its rivals despite topping the timesheets in pre-season testing.
Alonso was delighted with how the car performed in testing and but he is refusing to take anything for granted ahead of what is expected to be a wide open season.
Ferrari's performance over the winter has resulted in the Italian teams being named favourites for 2010 but Alonso insists he, nor the team, have any interested in being crowned world champions in March when there are ten months until the title is handed out.
"We are not comparing too much the times in winter or making any predictions for this first race, we are concentrating on our programme, trying to be as good as possible for the first race," he said.
"I think the four teams, Red Bull Racing, Mercedes, McLaren and Ferrari, any of the four teams can be a favourite for this race and the first part of the championship. And teams like Sauber and Force India will have very good races as well.
"We will do our best, we are well prepared but we want to be world champions in November - not March. The goal is to win the championship, this is not easy at all and we need to work very hard for 10 months."
