The twin Mercedes of Nico Rosberg and Lewis Hamilton have so dominated the Formula One circuit this season that even a second-place finish that extended Rosberg's lead in the championship standings left them disappointed.

"We need to make sure that we're bulletproof," Rosberg said after Daniel Ricciardo passed the hobbled Silver Arrow with two laps to go to win the Canadian Grand Prix on Sunday.

"Having lost the win, that's very, very disappointing, definitely, and also disappointing for us as a team. We have such speed and such a great car, to not win the race and even just finish with one car and come second is hugely disappointing for us, definitely.

"Our ambition is to finish one-two so we need to make sure that we get back there again next race in Austria."
