Former Formula 1 driver and Sky Sports Germany analyst Ralf Schumacher has branded Kimi Antonelli's Canadian Grand Prix sprint race radio outburst as "one step too far", but insists that such fiery behaviour is essential for a future world champion.
Antonelli argued that his Mercedes team-mate George Russell had forced him off the track as the Italian attempted an overtake around the outside on lap six. The 19-year-old, who became the youngest driver to lead the championship after the Japanese Grand Prix, fumed over the team radio.
