George Russell topped the times for Mercedes after Charles Leclerc crashed his Ferrari during Friday’s second practice at the Mexico Formula One Grand Prix. 
Russell offered a hint of Mercedes’ potential with a strong performance in a session devoted to tyre testing, in changeable conditions, while Leclerc, unhurt, was left to watch from the Ferrari garage. 

The Briton, 24, took advantage of a chance to shine as one of only a few drivers permitted to run on 2022 tyres and clocked a best lap in one minute and 19.970 seconds on softs.
