Lewis Hamilton told Sebastian Vettel they would have "problems" if the Ferrari driver ever repeated his controversial car chop from the Azerbaijan Grand Prix, the world champion has revealed.
Baku's chaotic and thrilling street race saw the major flashpoint of Hamilton and Vettel's title fight, when the latter pulled up alongside Hamilton as he slowed the pack ahead of a Safety Car restart. Apparently incensed by how slow the Mercedes driver was going -- he had driven into the back of Hamilton's car at the previous corner -- Vettel raised a hand, before driving into the side of the silver car in protest.
