World champion Lewis Hamilton was maintaining his sunny disposition on Thursday, despite admitting that his five-place gearbox change penalty was "a kick in the goonies".

However, the Mercedes driver was still notably upbeat, as Spanish daily Marca quoted him as saying in Shanghai: "It's not ideal, but it happens.

"I see it as a challenge and therefore another opportunity, so it's glass half full rather than half empty.

"It's better to take the penalty here because it's easier to overtake than at some of the tracks that follow."

Teammate and championship leader Nico Rosberg is also refusing to write Hamilton off, saying: "The penalty makes it more difficult for him, but we know that Lewis can always fight for victory."

Rosberg's first pole and win came in Shanghai, but Hamilton is also a specialist of the Shanghai layout.

"I don't know why but I feel good when I drive here," the Briton admitted.

The Chinese Grand Prix gets underway at 7am BST on Sunday.
