Max Verstappen has earned a fearsome reputation as a fine, aggressive overtaker since he came into Formula 1. But the Red Bull driver's defensive tactics are coming under increasing scrutiny following another incident with Ferrari's Kimi Raikkonen at the Belgian Grand Prix.
This latest controversy follows a heated battle during July's Hungarian GP, where Verstappen twice made late defensive moves that caught Raikkonen out. In each case officials have seen no reason to act, yet Verstappen's actions have provoked criticism from his rivals.
A genuine grievance, or just fragile egos struggling to deal with the meteoric rise of a new superstar? Probably a bit of both. But there's no doubt Verstappen is treading a very fine line.
