Nico Rosberg insists he won't change his approach to the Chinese Grand Prix, even though his team-mate Lewis Hamilton has been hit with a grid penalty.

Hamilton has been given a five place drop after Mercedes opted for a precautionary gearbox change, a result of damage sustained during the Bahrain Grand Prix.

Asked if that will now make winning the event easier, Rosberg replied: "I mean I have taken notice of that but it hasn't really changed my approach at all because a Hamilton that starts sixth is still going to challenge for the win and we know that, so from that point of view it doesn't really change much for me.

"I'm still fully focused and not taking anything for granted at all, because not only him there are still Ferrari who haven't shown at all what they can do yet, we mustn't forget that, there's a lot more in them because they've had such a messy first two races, it couldn't have gone any worse really for them, so I know that as well, and therefore I am fully focused for the attack and looking forward to any battle that may arrive."

After winning the two races in Australia and Bahrain, Rosberg arrives in China with a 17-point lead in the Drivers' Championship, but doesn't believe that lady luck is necessarily on his side.

"That's an easy one to answer - it's two races into the longest F1 season we've ever had with 21 races, so thoughts like that don't come across my mind because it's just massively early days. It's been two races and yes I am really happy how it's gone but I'm battling Lewis Hamilton, and we all know how quick he is and his track record in the last two years, and that's not going to be any different this year, he's as focused and as motivated as ever internally, so there we go."
