George Russell took aim at Max Verstappen for his "pathetic" response to their on-track tussle in Azerbaijan last weekend.
The pair made contact on the first lap of the Sprint race in Baku, leading to some angry shouting over the radio from Verstappen. And he was not done there, confronting the Mercedes racer after the end of the Sprint to complain about the collision and call the Brit a "d***head".
Russell brushed off that insult at the time and remained cool about it when speaking to reporters on Thursday in Miami. But he used some much stronger words when asked about the incident in a Sky Sports interview.
