Hamilton will dig the night overnight his advantage Friday

Lewis Hamilton aims to win a sixth British Grand Prix record this weekend. However, based on Friday's time at Silverstone, his teammate Mercedes, Valtteri Bottas, might have something to say about it.

Hamilton, who could surpbad Jim Clark's five home victories on Sunday, was overtaken by Bottas in the day's two practice sessions, finishing fourth in the Finnish race in second place at FP1 and second at first.

And after struggling against the wind conditions and the new surface of the track, the world champion title has no obvious explanation for this deficit, admitting that he will have to find answers before qualifications to reform his colleague and stay in front of the Ferrari.

"The asphalt is very smooth, which makes it difficult for the tires to work properly. They come in and out of the window and the gusts of wind have not made it easy, "Hamilton said. "I struggled with the back and left several times.

"Valtteri seemed much more comfortable in the car, so we're going to dig deep tonight to figure out what the problem is and how we can fix it for tomorrow.

"The days were not the easiest, but we were still up there and it looks like we will be fighting. However, it is still difficult to say after the first day and the Ferrari are usually a little slower on Friday, then accelerate the pace on Saturday. "

Despite his concerns, the gap between Hamilton and Bottas was not huge this Friday, just 0.069 to be precise, although his teammate think he can also gain more speed on Saturday.

"The car looks pretty well balanced, but I think there is still room for improvement," said Bottas, winner of the Grand Prix five times, currently second behind Hamilton in the overall standings with 31 points. "The turns were fast and there are a lot of bends at Silverstone, so that's a good thing.

"I still think we'll be close tomorrow and it will be who will find the most performance tonight and tomorrow before qualifying, but it's good to start the weekend on a positive note."

Hamilton and Bottas each have three poles in 2019. Who will be the first to four?
