Only a "very, very lucky" situation will see Mercedes win a race this year, according to Michael Schumacher.

But after his podium at Silverstone, his teammate Nico Rosberg has a different view.

"We have made a giant step forwards," the younger German is quoted by Bild newspaper. "I can promise more."

Seven time world champion Schumacher, 54 points behind his younger teammate and ninth across the finish line in Britain, is less optimistic.

"We will have to be very, very lucky to get a victory," he added.
