A former Formula 1 race winner has tipped George Russell to be a "handful" for Lewis Hamilton, and told the seven-time world champion he needs to "lift his game".
Russell's rise has been a sharp one, impressing with Williams to earn his shot at Mercedes and the general consensus that he is a future F1 world champion. To do that, in the next couple of years at least, he will need to usurp team-mate Hamilton as top dog within the team.
That will not be easy, despite a strong debut season which has seen Russell outscore his much more experienced team-mate so far. Hamilton has voiced his desire to continue racing for years to come despite approaching his 38th birthday, and wants to help the team to return to regular contention for race wins.
