Max Verstappen raged over the radio to his Red Bull engineers after what he felt was a pointless pit stop during the British Grand Prix.
The Dutchman started the race second, and by lap 10 he took advantage of a mistake from Carlos Sainz to take the lead of the race. It didn't last long, though, as he picked up a problem when he ran over some debris on the track.
At first he thought it was a puncture, and duly came into the pit lane for a change of rubber in the hope that would make the difference. But it didn't as he continued to lose time compared to those around him.
