George Russell up for the fight as he sets sights on reeling in Mercedes teammate | Giles Richards

Engine failure in Canada is latest setback for British driver, who is 43 points behind teenager Kimi Antonelli after five races

George Russell was left wondering quite which deity he had offended as he despairingly contemplated his retirement from the Canadian Grand Prix with a mechanical failure. Fortune, for good or ill, will always play a part but what also became clear in Montreal is that Russell's teammate and championship leader, Kimi Antonelli, is going to be fearsomely hard to beat this season, whatever the circumstances.

Russell ground to a halt on the circuit Gilles Villeneuve on lap 30 after a thrilling battle with his Mercedes teammate that had ebbed and flowed. The British driver deserved better, the two had been exchanging the lead and going side by side repeatedly, inches apart and trading paint on one occasion, only for Russell's efforts to count for naught as he went out not with a whimper when the systems on his car shut down due to battery failure.
