Ferrari team principal Stefano Domenicali dismissed predictions of infighting when Fernando Alonso and Kimi Raikkonen combine as teammates next year, saying such talk is being waged by jealous rivals.
Many leading figures of F1, both past and present, have predicted friction between the two leading drivers, but Domenicali said he thinks they are simply worried about Ferrari's potential improvement.
"Maybe they have fear, because we are strong," Domenicali said on Thursday ahead of the Singapore Grand Prix, adding that this was "part of the game, part of the psychological war of this environment."
He also praised outgoing driver Felipe Massa for accepting his departure "with a serenity he showed which is not common in this world."
Raikkonen said both he and Alonso were mature enough to be able to resolve any problems that may arise between the two world champions.
"I don't see the reason why it would not work," Raikkonen said. "We are all old enough to know what we are doing. ... If there is something, I am sure we can sort it through."
