British GP: Sebastian Vettel Unconvinced by Ferrari's Strong Form in Practice

Sebastian Vettel was unconvinced by Ferrari's strong form in Friday's free practice sessions for the British Grand Prix and forecast that Mercedes will improve and pull clear in qualifying on Saturday.

The four-time world champion and his Ferrari team-mate Finn Kimi Raikkonen were third and second respectively, splitting the two Mercedes of pace-setter German Nico Rosberg and defending two-time champion Briton Lewis Hamilton who was fourth. (British GP: Nico Rosberg Left Underwhelmed)

"I don't know what happened to them (Mercedes)," said Vettel.

"I think you saw the pace in general of them in the long run and this morning so they will be quick no matter what. (Vettel Wants Raikkonen to Remain With Ferrari Next Season)

"Anything else will be a surprise, but if we can repeat our form tomorrow, that will be good news for us.

"We didn't have any issues with the car and we more or less got through everything that we wanted to do. I'm not entirely happy yet with how the car feels, but I think for tomorrow we can make a step forward.

"I think we can improve. We tried a couple of things and now we have to find out what was good or what was bad and put all the good things in the car for tomorrow.

"We didn't have anything going wrong with the car. This track is a lot about finding the rhythm, so it was good to do a couple of laps."
