Pat Fry and Nikolas Tombazis will leave Ferrari after the team announced a restructuring by new team principal Maurizio Arrivabene.

Engineering director Fry and chief designer Tombazis are set to leave the team after a poor season which saw Ferrari score just two podiums and finish fourth in the constructors' championship. It's the latest change in a year of turmoil at Maranello, with former team principal Stefano Domenicali being replaced in April and his successor Marco Mattiacci only lasting until the final race of the season.

Fernando Alonso has also left Ferrari - with Sebastian Vettel joining for 2015 - while perhaps the biggest change this year saw president Luca di Montezemolo replaced following the Italian Grand Prix in September.

As part of the latest shake-up, technical director James Allison will be supported by chief designer Simone Resta and power unit director Mattia Binotto as the team looks to promote the presence of Italian engineers. Allison will also take on track engineering activities on a temporary basis.

Noting Allison's added responsibilities, a Ferrari statement said: "Therefore he will be responsible for all technical aspects of delivering the Scuderia's drivers Kimi Raikkonen and Sebastian Vettel, as well as the newly appointed test driver and third driver Esteban Guti?rrez, with the most competitive Formula 1 car possible."

Massimo Rivola will manage Ferrari's F1 activities, while Arrivabene himself will manage the newly-founded commercial department on an interim basis. Renato Bisignani, previously head of the Ferrari press office, will join the new department as marketing manager. That leaves the press office to be run by seasoned F1 journalist Alberto Antonini, with the TV commentator for RAI and Sky Italia also overseeing the newly created Scuderia Ferrari digital team.
