A number of drivers have complained the track surface at Suzuka is making for challenging conditions at the Japanese Grand Prix.

Lap times started to drop off during the long runs in a sign of high degradation levels, with multiple drivers saying they were sliding through the first sector on race simulations. George Russell was fifth quickest overall but said he was caught out by the way the track was performing on Friday.

“There seems to be a huge amount of tire degradation,” Russell said. “It’s really weird — Suzuka is one of the best tracks in the world to drive, but this year it feels like the tarmac has really broken up and the cars are sliding on top of the surface. It’s giving a bit of a strange feeling to all the drivers out there, and that’s what’s contributing towards that tire degradation.”
