Antonelli tops Russell in chaotic Canadian GP practice

World championship leader Kimi Antonelli maintained his superb form by outpacing his team-mate George Russell in Canadian Grand Prix practice as Mercedes produced an ominous display with their upgraded car.

Having won each of the first four races of the season, Mercedes delivered a statement showing in the sole practice session of the weekend after bringing their first major upgrade package of the year in Montreal, establishing themselves as heavy favourites for Sprint Qualifying later on Friday.
