Mercedes driver Lewis Hamilton has admitted that his chances of winning the Formula 1 world title have "totally gone out the window" following his disappointing display at the Singapore Grand Prix.

The Brit failed to make up any positions at Marina Bay and finished where he had started on the grid in fifth place.

Having watched his rivals Fernando Alonso and Kimi Raikkonen climb high up the track proceedings, Hamilton believes that his side did not do enough on the day.

"I don't think we can come away from this weekend satisfied," Hamilton told Sky Sports News. "I thought we were further ahead - I didn't see my pit board and no one told me what position I was in, so I thought with Mark [Webber] dropping back we were progressing, so it was disappointing to get the result that we got considering how hard we were pushing.

"Maybe the strategy wasn't the best, but nevertheless the guys did a great job and I hope at the next race we have a better chance. I would say being 100 points behind now that that has totally gone out the window.

"We just have to try and catch Fernando somehow. He is ahead so we have to beat Ferrari and try to ride the wave that we are on as a team - it is a much better wave than they were on last year. So we just need to concentrate and get the Ferraris."

Hamilton trails leader Sebastian Vettel by 96 points in the drivers' rankings.
