Mercedes' Lewis Hamilton (fifth on the grid):
"It's going to be very tough, for sure, but we are going to give it our best shot.
"It's a little bit cooler today which might help with the tyres but we have not figured anything out with them.
"I am fighting for the win - I am going to give it hell."

It is just starting to get dark in Singapore so the race will get under way under the lights at 13:00 BST. You will be able to listen to 5 live commentary from that time, on the radio and online.

Image source, Getty Images“A bit more on Mercedes’ struggles. What has been seen in Singapore is, in effect, like Mercedes losing the best part of two seconds a lap in the two weeks since the Italian Grand Prix. Even in the context of great F1 surprises, that takes some swallowing.
“Neither driver said the car felt bad; quite the opposite. Rosberg said: ‘I just looked at Sebastian’s onboard in the debrief and I didn’t mean to, but I shouted out, “What the..?” It seems like he is on a different planet sometimes.’
“Hamilton, meanwhile, said in his news conference: ‘It’s a bit like doing a good lap on the prime tyre and then you go and do exactly the same lap on an option tyre and it’s a second and a half faster. I do the lap, and like, ‘that was a really good lap’, but it’s a second and a half slower than the guys up ahead, so....
“‘We’ve not lost any performance in the car, the drivers have not lost any performance, and so there’s only one way it can come from and that’s obviously the rubber. But I have no way of knowing that is the case, so I’m very interested to find out. I actually challenge all you guys to go and find what the reasons might be, and I’m challenging my team to find out where we’ve lost time – whether it’s in tyre pressures, temperatures of blankets, ride heights, I’m challenging everyone to find out.’
“F1 is a world of many mysteries, some darker than others. Make of those comments what you will.”
Your podium predictions
Not a single Mercedes driver predicted to be on the podium? What a time to be alive!
Held in a futuristic city and at night, there is always a party atmosphere in Singapore, an atmosphere that is only heightened by the stellar names that perform at the nightly concerts as part of the grand prix weekend's entertainment.
So far in Singapore, there has been nothing for Lewis Hamilton to be 'Happy' about...

...but for Sebastian Vettel, everything about it has been pure 'Gold'...

“What has gone wrong for Mercedes this weekend? Well, the simple answer is tyres. Lewis Hamilton said: ‘We just haven’t been able to get the tyres in the (operating) window. They just weren’t switching on.’ That was the what. The bigger question, though, was why? And to that Mercedes had no answer, the engineers admitting they were scratching their heads.
“Doubtless there will be an intense post mortem ahead of the Japanese Grand Prix next weekend, but for now there is a race to be run. Pole-sitter Sebastian Vettel said he would not rule out Mercedes challenging for the win - ‘if you have the pace, you eventually come through,’ he said - and on the face of it, even if the tyres did not work for Mercedes over a single lap, they should be able to make them ‘come in’ in the race.
“But Mercedes do not sound optimistic. Team boss Toto Wolff said he ‘wouldn’t expect anything really positive’ and executive director (technical) Paddy Lowe - the big cheese when it comes to car performance - said: ‘We will be aiming to fight back in race conditions, but we also need to be realistic about where we stand this weekend.’”
I think we can say with a strong degree of certainty that this will be the toughest race to predict all year. Can either Lewis Hamilton or Nico Rosberg come through for victory? Or will it be a Ferrari or Red Bull driver celebrating?

Quote MessageOn a circuit which is so tough for the cars and drivers, and where overtaking is difficult, we shouldn't expect miracles. It is going to be a day for damage limitation.

Quote MessageWe got the first indication that Ferrari have really started to up their qualifying pace in Monza, where they were within two tenths of the qualifying time of Mercedes. It does look like this weekend Mercedes will just be trying to salvage some points.

"Not unlike when Fernando Alonso won in Malaysia in 2012 two weeks after qualifying 12th in Australia, or when the McLarens of John Watson and Niki Lauda finished one-two in Long Beach in 1983 after starting 22nd and 23rd, no-one - but no-one - would have predicted heading into this weekend what happened in qualifying at Marina Bay on Saturday.
"Even in a year such as this, this amazing sport never loses its capacity to thrill and delight."
Image source, Getty ImagesHello! Welcome to our coverage of the Singapore Grand Prix.
So often this season it has felt like all Mercedes have had to do is turn up to a race and they were pretty much guaranteed of being in prime position to fight for victory come Sunday.
Not so this weekend.
Ferrari's Sebastian Vettel starts on pole, with the Red Bull of Daniel Riccardo alongside him on the front row.
Even then there is no Mercedes behind them, with Lewis Hamilton and Nico Rosberg lining up fifth and sixth respectively.
Make no mistake, Mercedes have a bit of work to do...
There are a few things that we have become accustomed to seeing in Formula 1 these days.
Things like, Daniel Ricciardo smiling...
