The Scuderia has lost its highly-rated race director Laurent Mekies, who will join AlphaTauri as team principal. Meanwhile, head of vehicle concept David Sanchez has switched to McLaren.
Team boss Vasseur has moved to hire Mercedes performance director Loic Serra. However, contract lengths mean he will not officially join until 2025.
Vassuer has said further announcements concerning signings will come soon but the former Renault and Sauber F1 chief says he will “never accept” that Ferrari's success is contingent on these newcomers.
Vasseur told select media ahead of the Dutch Grand Prix this weekend that he was “frustrated” due to the time taken to change a team’s fortunes: “[Recruitment] is a very long process.
“The consequence of this is that also the people joining sometimes in a couple of months - we have people starting in the company 1 January 2024, 1 July 2024, some will start the beginning of 2025 – is a very long-term process.
“Somehow, it's a bit frustrating also because you have the feeling that you are working for two to four years from today. But if you don't start to do it, you will never get it.
“It means we have to push on it. I think we made a good step forward.”
