Jenson Button says he doesn't believe Red Bull and Ferrari have made large steps forward in China, just are more suited to the circuit than McLaren.

Daniel Ricciardo qualified in second place ahead of team-mate Sebastian Vettel in third, with Red Bull looking set to give Mercedes a run for its money in today's Chinese Grand Prix. With both Ferraris ahead of the two McLarens - as Button and Kevin Magnussen dropped out in Q2 on Saturday - Button feels the weekend has been one which has suited some teams more than others regardless of their outright pace.

"Here you would say the Ferrari is pretty competitive - more competitive than us - and the Red Bull is more competitive and those two have made a step forward," Button said. "But have they really? Have they really put that much on the car or is it just the layout of the circuit, the temperatures and the conditions?

"So it's going to change a little bit every race I think, and if you look at the last race the Force India was reasonably good at the start of a stint but would not be so strong at the end of a stint, the Williams was very quick but had to do three stops because it was destroying its tyres, and we were quicker at the end of a stint.

"So it's going to change all season I think. There's a very close pack that are fighting for that P3 on the podium at the moment behind the two top cars and we have to make sure that we get the best out of what we have every race weekend.

"We didn't do that in Bahrain because we had the problems, but we've got to keep bringing the updates - which we are and will be at the next few races - and best of the rest is as good as it's going to get right now until we make the big leap to Mercedes, but we're positive we can fight the rest of the field in the next few races."
