Mercedes driver George Russell said he was "lost for words" after retiring from the Formula 1 Canadian Grand Prix lead, but said he "loved" his intense battle with team-mate Kimi Antonelli.
Russell and Antonelli had been trading the lead until power unit trouble saw Russell coast to a halt on lap 30, handing Antonelli a comfortable drive to his fourth consecutive grand prix win. As a result, the 19-year-old Italian expanded his title lead to 43 points.
