Off to a flyer 🏎💨 Mercedes’ George Russell, a stand-in driver after Lewis Hamilton’s positive test for Covid-19, was the fastest in both practice sessions at the Sakhir Grand Prix on Friday. Russell has swapped from Williams to Mercedes this weekend and topped Red Bull’s Max Verstappen in both sessions in Bahrain. He admitted, however, that jumping into a new car at short notice had been “tricky” and that there was still a lot to learn (📸 Tolga Bozoglu/Pool/AFP/Getty Images). . . . #sakhirgp #formula1 #f1 #motorsport #bahrain #georgerussell #mercedesamg
