The futures of both Alonso and Raikkonen have been cast in doubt this year, with the Finn struggling to get to grips with the ill-handling F14 T on his return to Scuderia and the Spaniard linked with a return to McLaren in the wake of another disappointing year at the Italian outfit.
However, Mattiacci has insisted to Sky Sports F1’s Martin Brundle that both drivers will remain with the team for next year.
The interview will be played in full as part of Sky F1’s coverage of the Belgian GP from 11.30am on Sunday.
2007 World Champion Raikkonen remains Ferrari’s last title winner while Alonso is regarded by many in the paddock as the best driver on the grid and their union, at the expense of the ousted Felipe Massa, was expected to signal the Scuderia’s revival this term.
There have also been structural changes this season. Aside from the aforementioned Mattiacci, who took on the Team Principal role after Stefano Domenicali resigned, Luca Marmorini left the team’s engine division last month
