Lewis Hamilton's comments about Formula One rival Max Verstappen suggest the Dutch driver is beginning to get to the seven-time world champion, Red Bull team boss Christian Horner said Thursday.
Hamilton, the sport's most successful driver of all time with 100 pole positions and 98 wins, suggested at the Monaco Grand Prix that, unlike him, Verstappen "feels perhaps he has a lot to prove".
Red Bull's Verstappen, Hamilton's closest challenger, said he had nothing to prove.
