Felipe Massa backs calls to shorten F1 weekends to two days

Last month, the United States Grand Prix weekend was compressed following heavy rain on Friday and Saturday, with qualifying being run on Sunday morning before the race.

Ferrari's Kimi Raikkonen said after the race he was in favour of fitting everything into two days, potentially with all three practice sessions on Saturday and qualifying and the race on Sunday.

Meanwhile, Nico Hulkenberg has suggested previously there is too much time set aside practice in F1.

But while Massa believes a compressed format is a realistic goal, he wants to find a way to allow teams to complete more mileage during the weekend.

"I have no problem taking out Friday," said the Williams driver. "I would not have any problem with that at all.

"On Friday, nothing happens, especially if you have bad weather.

"I think it would be nicer to have more cars running all the time.

"You can do the practice sessions on Saturday morning and qualifying on Saturday afternoon.

"Then if you have a big water problem on Saturday, you can move qualifying to Sunday.

"But that would happen very few times, if it happens."
