Lewis Hamilton feels Mercedes are lacking speed on the straights which was the main reason they lost out to Red Bull and Max Verstappen at the French GP.
Hamilton finished second at Paul Ricard after Verstappen overtook the seven-time world champion with less than two laps remaining.
“We’ve got to find some pace that's for sure,” said Hamilton after the race. "Most of the time we lost today was just on the straights, so we've got to definitely dig deep and try and figure out where that is and whether it's power or drag but we’ve still got a good package.
“What was really surprising too was the wear on the left front tyre so early on. But obviously they just had a good strategy and it worked really well.
“Of course we didn't win and we were in the lead but I had no tyres left at the end so unfortunately lost the position but still, it was a good race.”
Verstappen used a surprise two-stop strategy to overcome Hamilton and the Mercedes driver believes he had no option other than to try and nurse his hard tyres to the end of the race.
“He was already quite far ahead so the only option I really had was to stay out,” said Hamilton. “Otherwise I would be pitting because he's again undercutting me so he would just come out ahead and I wouldn’t be able to get past because they are too quick on the straights.
"The only option was to stay out as long as possible and hope the tyres hold together. I think considering that we had such a difficult Friday I'm really happy with today's result."
