I couldn't understand why Nico didn't overtook him. He is to long in F1 to be a puppet. It was the most stupid behaviour from him.
He's following instructions from the team. If your boss gave you an order at work to do something, and you didnt listen to him, you would be fired.
Is he really able to be a Champion?
Well we have seen in Australia and in Malaysia that Rosberg has been pretty much on par with Hamilton throughout the weekends. I think he is well able to race him and yes, he could well be a championship contender if Merc can get an upper hand over Red Bull, which could well be next year with all the rule changes.
