Daniel Ricciardo insists he is 'not discouraged' by the margin to Mercedes at the end of FP2 for the Singapore Grand Prix, but admits it may take some 'luck' for Red Bull to snatch pole position in the Marina Bay.

The Australian was just 0.049s behind pace setting team-mate Max Verstappen in FP1, but four tenths down on Nico Rosberg in FP2 en route to the fourth fastest time.

With his progress hampered by a spin early on in FP2, Ricciardo was satisfied with his performance despite losing pace on the ultra-soft tyre before the end of the lap.

"We had to work for it today. We can find a few things tonight. I am not discouraged the pace. Where we are is pretty good considering where I feel we can be with the car.

"The ultra-soft is a funny one. It is so straightforward. You think you have the grip and it goes away. So we will look into it. We lost a lot quite a lot in the last sector. I could feel that it was a bit scrappy, but there are probably some things I could improve there."

"There is still a lot more we can get out of it. So if we find that, then we will be looking alright tomorrow, but it is close as predicted - three teams all there within half a second."

Even so, Ricciardo admits he doesn't believe Red Bull quite has the car capable of pole position but is optimistic there is time to find in the car.

"I think at the moment we're not quite there where we need to be, I think we're close enough, I think with what we've got we'd probably have to get a little bit lucky to snatch pole. I think we need to just find a little bit more in the set up, I know the car quite well now so I know there's a few things on it which can be better so hopefully we jag that tonight and prepare it well for tomorrow.
