Sparks flew over the airwaves in the Mexico City Grand Prix as George Russell butted heads with his race engineer on Mercedes' team radio.
After a "frustrating" race at the Autódromo Hermanos Rodríguez, Russell shed light on the delay in team orders that left him stuck behind rookie teammate Andrea Kimi Antonelli.
The tension crept in on lap 35, when Russell radioed for permission to pass Antonelli, saying:
"We got a Ferrari and a Haas ahead, we can fight for the podium here!"
Mercedes' response was a "free to race" call, but no firm team orders to let him pass, which had Russell seeing red by lap 38.
