Mercedes has won four straight championships under Formula 1's current rules, and Formula One's managing director of motorsport Ross Brawn is worried that it will continue.
"They've got a great group of people, but my slight worry is that they will get even stronger now," Brawn told ESPN. "They've had a change of senior management -- Paddy Lowe left and James Allison came -- and that was in the middle of a car [regulation] change, which is not easy.
"By their own admission, the car they had this year was a bit of a diva and I strongly suspect that's not going to be the case next year. So I just see -- unfortunately in many ways -- a continuation of the steamroller. Let's hope I'm wrong!"
