Grumbling Verstappen knows after just one session there's a problem: 'Incredible...'

Verstappen's gap to Lewis Hamilton's fastest time on the soft tyres was 0.540 seconds. That he was not satisfied with his car was clearly conveyed over the team radio by the four-time world champion.

Grumbling, Verstappen said: "I don't know, it just doesn't turn at low speed, and then any high speed, it's either big snaps, pile of understeer."

Shortly after, he exclaimed 'Unbelievable' over the radio, referring to the difficulties of the Red Bull Racing car.

During the debrief, Verstappen will undoubtedly elaborate on what went wrong during the first free practice. He will likely also share his thoughts on the updates his team brought to Silverstone.
