Fernando Alonso would be faster than Sebastian Vettel at Red Bull, that is the claim of Mercedes driver Lewis Hamilton.
The Briton, who admits he doesn't particularly like the German despite having respect for his achievements made the comments speaking to Spanish newspaper Marca.
Recently on Twitter, Hamilton said of Vettel: "Feel the need to clarify my thoughts," he wrote on Twitter earlier this month. "Seb is great champion!"
But asked by the Spanish sports daily if he would have won four titles if he was at Red Bull, Hamilton replied: "I can't really say.
"It would be foolish of me to say that," he added.
"But what is clear to me is that if Fernando (Alonso) had been in that car ... he would be far beyond where Vettel is now. He would have won even more easily."
That view is not shared however by his team's chairman, triple world champion Niki Lauda, who is full of praise for Vettel who will likely surpass his three titles this weekend in India.
"If the good lord had mixed a cocktail with all the best features of a racing driver," Mercedes' Lauda told Auto Bild, "Sebastian Vettel is the result."
The biggest thorn in Vettel's side appears to be his team's chief designer Adrian Newey with many people put the 26-year-old's success down to his car as oppose to him.
Asked about why there is a lack of respect for Vettel, Newey put it down to "jealousy", however the former Williams and McLaren designer admitted he could be entering the twilight of his F1 career.
"I'm 54 now," Newey told the Telegraph, "and there are lots of other things I would like to be involved in.
"Maybe the America's Cup, who knows?" he added.
Though Newey did admit that would like not be in the immediate short term.
"It's a bit too late (for 2014) isn't it?" he said. "My immediate future lies in Formula One. I'm fully committed to next year and the new regs."
Widely recognised as perhaps the greatest F1 designer of all time, Newey's boss at Red Bull Dietrich Mateschitz could be considering putting an America's Cup team together himself with the Briton leading the design team.
"Maybe," Newey answered. "It's not something I have spent a lot of time talking to Dietrich about I'm afraid."
