Lewis Hamilton could be replaced by Ferrari if Max Verstappen leaves Red Bull, a former Red Bull figure has teased.

After the first two practice sessions at the Bahrain Grand Prix, Verstappen is again sounding the alarm. Verstappen sat out the first practice session, as Red Bull handed over driving duties to reserve Ayumu Iwasa to satisfy one of four required rookie driving sessions on the season.

Red Bull's Max Verstappen has said his brakes and an overall lack of grip led to his underwhelming qualifying position in Bahrain.
