Marco Mattiacci has repeated his claim that Ferrari is keeping its driver lineup for 2015.
That is despite intense speculation particularly about the future of Spaniard Alonso, who is reportedly disgruntled after five years of failing to win a third title with Ferrari.
Following the Sky report, the correspondent for the Spanish sports daily Marca, Marco Canseco, also asked Mattiacci to 'confirm' Alonso and Raikkonen for 2015.
"If you want, I can confirm them to you," Mattiacci responded.
"Both have contracts and there is not much to say on this matter other than that they are the two best drivers for us."
At Spa Francorchamps Circuit last weekend for example, Alonso and his manager were spotted entering the Red Bull motorhome, amid wild rumours Sebastian Vettel could be lured next year to McLaren-Honda.
Canseco acknowledges the official story that Alonso was simply asked by the Red Bull engineer Paul Monaghan, formerly of Renault, to sign a t-shirt for his son.
