Former Benetton and Renault team manager Flavio Briatore believes that Lewis Hamilton and Formula One rival Sebastian Vettel could not work together and be teammates.
Hamilton and Vettel were the frontrunners for this year's Championship, in search of their fourth and fifth Formula One titles respectively.
And, it was Hamilton who came out on top this year.
His ninth-place finish at the Mexico Grand Prix was enough to secure him the 2017 World Drivers’ Championship with two rounds to go, after Vettel failed to finish in the top two.
Nine years after he won his first world title, the 32-year-old became Britain's most successful Formula 1 driver ever.
His fourth title meant that Hamilton equaled Vettel's Championships, as well as joined an elite group of Juan Manuel Fangio, Alain Prost, Michael Schumacher, and Vettel himself, who have also won the world title on four or more occasions.
Hamilton and Vettel’s rivalry escalated on numerous occasions this year, including the above mentioned Mexico City race when they collided in the first lap.
Hamilton has been linked with a potential move to Ferrari in the future, which would potentially mean him joining bitter rival Vettel in the team.
However, Flavio Briatore believes that despite the unquestionable qualities of the pair, they would not make a good team.
When asked by Italian broadcaster Rai on whether Vettel would be a good teammate for Hamilton, Briatore sounded negative.
"I do not think so, he cannot co-exist with Vettel. Alonso is still the best guy.
"With him and Vettel, Ferrari would have 100 per cent won the Constructors’ World Championship."
Briatore believes that motivation and focus were the key factors for Hamilton's success this term.
"This year he was very good, he was more motivated on the track than in the disco," he explained.
The 2017 Formula One season ends at Abu Dhabi’s Yas Marina Circuit on Sunday, November 26, and while Hamilton secured the title some weeks ago, Vettel is still in the fight for the No. 2 spot.
He is 22 points ahead of Mercedes' Valtteri Bottas and would need a top 10 finish in the last race to seal his second place in the Championship.
