Jean-Eric Vergne was offered a seat alongside Le Mans winner Nico Hulkenberg at Porsche for 2015, it has emerged.
"I just had to sign the contract," said the former Toro Rosso driver, who is looking to return to F1 next year with the new Ferrari-aligned entrant Haas.
But it was Frenchman Vergne’s role as a Ferrari test driver this year that ultimately scuppered his Le Mans hopes.
"Ferrari didn’t want me to, so I did not accept the offer," he told the French magazine Auto Hebdo.
