Hamilton celebration a win
Lewis Hamilton considers Sebastian Vettel to be a serious threat to his championship bid, but has hailed Ferrari's resurgence as 'great' for Formula One.

Hamilton remains the odds-on favourite to secure consecutive titles despite Vettel's victory in Singapore last Sunday.

With six races to go, the Ferrari driver is now 49 points adrift of 
Hamilton, who retired for the first time this season after a loss of power at the Marina Bay Street Circuit.
It marked Vettel's third victory of an impressive debut season with Ferrari after triumphs at the second race of the season in Malaysia and then in Hungary.

'How serious I take this challenge has not changed since Malaysia,' 

Hamilton said. 'For me, everyone is a threat and they have been since Malaysia. They won there so since then we have always kept them in view.

'When we got to Monza they took another step, so nothing has really changed for us. It is great for the sport.'

Hamilton's Mercedes team, who have dominated the sport for two years, were mysteriously off the pace in Singapore.
