Lewis Hamilton has revealed he told Formula 1 title rival Sebastian Vettel not to "disrespect" him again after their clash under the safety car during June's Azerbaijan Grand Prix.
Hamilton won the F1 Drivers' Championship at the end of last month, beating fierce rival Vettel to win the prize for a fourth time.
The two men have boasted a fascinating rivalry for years now, with the duo often fighting it out for the title.
Back in June, at the Azerbaijan Grand Prix, Lewis Hamilton finished behind the German after being hit by Vettel under the safety car.
And the Brit has now revealed he warned Vettel 'there would be problems' if the Ferrari man ever stepped out of line again.
In an exclusive interview with Motorsport.tv's The Flying Lap, Hamilton explained what he said to Vettel in private following the incident.
"When I spoke to him later, I was like 'that's a sign of disrespect, so don't ever disrespect me like that again otherwise then we will have problems'," said Hamilton.
