Vergne has told France's L'Equipe that Ricciardo's reputation is wrong.
Aug.12 (GMM) Jean-Eric Vergne, reportedly overlooked for the 2014 Red Bull vacancy, claims he has done a better job than Daniel Ricciardo this year.
The Frenchman conceded recently that the world champion team is more seriously considering teammate Ricciardo to replace Mark Webber because of the young Australian's superior consistency.
But Vergne has now told France's L'Equipe that Ricciardo's reputation is wrong.
"Red Bull is the world champion team and they need a driver who can score points in every race," said the 23-year-old.
"But if you look at the results, Ricciardo finished every race but I did not, and I have more points than him," Vergne insisted.
"But I have this image, even if it is false, but in the paddock Ricciardo is seen as more consistent than me."
Vergne complained that, of his multiple failures to finish races, on only one occasion was it his fault.
And he added: "If you look at the races that I had no problems, I thrashed my teammate -- he was nowhere."
Vergne's latest comments coincide with suggestions that, although Red Bull has said the Frenchman should get another season at Toro Rosso, the energy drink company is also keen to give Antonio Felix da Costa his debut.
He acknowledged that the decision-making process at Red Bull is complex.
"It's not that (team boss Christian) Horner takes the decision. Adrian Newey is also heard, as are Dietrich Mateschitz and Helmut Marko," said Vergne.
"I understand the risks of taking a young driver like me or Daniel. And it's even harder when they see a driver who does not finish all of the races."
