Jacques Villeneuve has criticised Lewis Hamilton and has said the Briton behaved like a 'spoilt child' after securing his third Formula 1 Drivers' title.
Hamilton had a dominant season, clinching the crown in Austin with his tenth victory of the year and with three races still to go.
However, in those remaining three races, it was his Mercedes team-mate Nico Rosberg that came to the fore, winning in Mexico, Brazil and Abu Dhabi, while Hamilton maintained his drop-off in form was related to set-up changes
made to the car after the team's struggles in Singapore.
“Lewis had a simple championship because we did not see the fighting, aggressive Nico from last year in the first part of the season,” Villeneuve said in an interview with Motorsport-Magazin
. “Nico began to do that only after the US GP, when Lewis reached his peak.
“Once he [Nico] lost the world championship, it seemed to change him, I don't know, but after he was a killer and Lewis reacted really badly and showed the negative side of his character.
“He showed he cannot be humble. He has won three world championships, but cannot rejoice and he behaved like a spoilt little child, who has had his toy taken away.
“He has since not behaved like a great champion.”
Villeneuve also warned that Hamilton should be wary about blaming the car for his drop-off in form: “He is the one who sits in the car. He is the one who works with his engineer. It is up to him. Whatever kind of a set-up they have got, it seems better for Nico now and maybe that is because Nico has worked at it,” explained the 1997 F1 World Champion.
“If that's the case, then Lewis was maybe not as superior as it looked - maybe he just had a set-up that was better. That's why he should be careful when he says something like that.”
Meanwhile, Villeneuve added that it was difficult to say why Rosberg seemed to lack that 'killer' instinct earlier in the season.
“I do not know [why that was the case]. The way the mind works is very complex. Perhaps it is because he has got his baby now and he is enjoying life. It was only when it was too late that he was again the aggressive Nico, like we saw last year, the Nico that can beat Lewis.
“If you take the last part of the season as a whole Nico was from race-to-race stronger, while Lewis was weaker. That is a fantastic feeling for Nico to take into the winter holidays.
“Nico has proven he can respond and Lewis has also revealed that when it comes to the crunch, he can stumble,” Villeneuve concluded.
