Valtteri Bottas isn't convinced Williams will have the race pace to take on Ferrari during the Chinese Grand Prix despite getting well amongst its rivals during qualifying.

Following a low key performance in free practice, Williams bounced back to form during qualifying around the Shanghai International Circuit, with Bottas and Felipe Massa lodging themselves between the Ferraris of Sebastian Vettel and Kimi Raikkonen in fifth and fourth respectively.

However, Bottas believes Ferrari's pace over long runs during Friday practice puts them in arguably a better shape for the race.

"I think in the race they, at least on the Friday long runs, they seem stronger than in one lap, so the tyre drop off is less than anyone else.

"We are somewhere in the average here, so it will be difficult but we are now between them and you never know what is going to happen in the race."

Despite the positive qualifying result, Bottas says he could have potentially gone faster had he not been overheating his rear tyres.

"Q1 we did the right thing with the tyres from practice, overall we had more grip from the tyres than in practice. But then in Q2 onwards, I really struggled with my rear tyres and I had to wind down the front flaps during qualifying which is opposite what we do when the track is getting better normally.

"We just tried to create temperature in the tyres, but after qualifying there was quite a difference between the cars in the rear temperatures. I was cooking my tyres too much on the out-laps and we only noticed after qualifying."
