Russell surprised at Mercedes being outpaced in Miami

George Russell admitted his surprise at Mercedes' streak of pole positions to start the season being ended by Lando Norris topping Miami Grand Prix Sprint Qualifying for McLaren.

Mercedes enjoyed a dominant start to the season, taking pole position and winning each of the first three races of the year, but a five-week gap since the Japanese Grand Prix has allowed rivals to bring upgrades that appeared to have a major impact on the first day of track action in Florida.
