Three races into the new season and Hamilton is yet to taste victory
and he finds himself nine points behind Sebastian Vettel, who has won
two races, in the standings.
The four-time World Champion looked well off the pace in Sunday's
Chinese Grand Prix and Rosberg admits it looks like he has lost a "touch
of motivation", but he says it is only a matter of time before the Brit
"Lewis was really struggling. He was struggling the weekend and
doesn't really understand, looking at his interviews (what is going).
"It's a typical phase for Lewis when it doesn't go perfectly and he
starts to lose that edge a little bit, lose a touch of motivation and
then he just struggles for a while. Usually he struggles for one, two or
three races, and those are the races when as his opponent in the
Championship you have to maximise.
"Sebastian failed to do that. That's a big setback for him as well
because Lewis always come back and when he comes back he comes back so
damn strong that he's almost unbeatable. Let's see when that happens."
Red Bull's Max Verstappen was another driver who missed out at the
Shanghai International Circuit as victory appeared to be there for the
taking, but he first made contact with Hamilton and then with Vettel.
Rosberg says it would have been a "painful" day for the Dutchman.
"He's one of the big talents out there and has a great future but
driving the way he is at the moment he's not going to be able to be
World Champion, because (he makes) so many mistakes," he said.
"Five mistakes in three races, and five major mistakes, it's too
much. (It) was one of those extremely hard days for a young driver where
if you take the Championship leader out, take yourself out, you get a
penalty, you are 100 percent at fault and your team-mate wins the race
in an unbelievably awesome way, that is a hard day, that's painful.
"Those are the days when a young driver like Max, hopefully for him, will learn and adapt."
