Former world champion Jacques Villeneuve has described Ferrari's decision to sign Kimi Raikkonen for 2014 as "completely insane".
Raikkonen was the last driver to win a driver's world championship with the famed Italian team back in 2007 though after that his performance slumped and he was replaced by the man he will partner there next season, Fernando Alonso.
The always outspoken Villeneuve believes that Ferrari's decision to re-hire the Finn will backfire.
"Ferrari are completely insane," the Canadian told the German newspaper Bild.
"He can drive a car fast, but he can't work with the engineers, he can't develop the car, he won't go to sponsor appointments," Villeneuve said.
Villeneuve is not the only one questioning the decision.
"If Kimi starts outqualifying Fernando that would be a big one," McLaren's Jenson Button said this week, "because Fernando is not the quickest guy but as a package he's exceptional.
"It's fun for us watching from the outside, but does it make the team stronger? I personally don't think it does," the 2009 world champion added.
Former Ferrari Rene Arnoux also added his name to the list of those who believe the Alonso- Raikkonen partnership could spell trouble at Maranello.
"It will last 3 or 4 races," said the Frenchman, when pondering the 'peace' at Maranello at the very beginning of 2014.
"As far as character, I see Alonso's as the weaker," he told Italy's La Gazzetta dello Sport.
"Remember him with Hamilton at McLaren? The peace was short lived, and while I am the first to hope I am wrong, for winning the constructors' title you need two very strong drivers and characters.
"But, of these two, one is angry and one doesn't care. Every Sunday there is the possibility that it explodes.
"Yes, as a neutral spectator, I like Ferrari's choice," he smiled.
The Frenchman however does believe that Raikkonen can get the upper hand over Alonso at Ferrari.
"He seems to be more mature these days. Sure, his character is still the same, but since he was at Lotus he seems more consistent.
"(Romain) Grosjean is still a mid-level driver and so it seems that Lotus has relied almost exclusively on Kimi," he added.
Arnoux also questioned whether Alonso can cope with being paired with a driver of Raikkonen's calibre.
"Definitely he has a bad temper, but this can also be a quality when it is used in battle," he said.
"But not when it is used within the team, creating difficulties and divisions.
"Frankly, I want to see if Alonso is really up to what people say about him. In Barcelona he did an amazing race, a masterpiece, but then for a few races he did nothing," added Arnoux.
As mentioned by Villeneuve, Raikkonen is well known for negotiating contracts that include minimal PR work away from the track, some are asking if that would add to Alonso's workload potentially adding further fuel to a potential fire.
This week Ferrari President Luca di Montezemolo said: "I hope his (Raikkonen's) public relations will consist of wins, as well as a contribution to the team and a diligent presence in Maranello.
"Alonso cannot take all the work on his shoulders alone," he insisted
