In the near future, teams such as Ferrari will be obligated to run under a much reduced budget. What better man to spearhead this change in the race team? Flavio has won titles on budgets much less than Ferrari, and that becomes very relevant.
I doubt whether Ferrari have people in-house capable of this difficult transition, they just don't have the experience in this area. But when the day comes when Ferrari will have to cope with a small budget, Flavio has a very good idea of what programs to keep, and what fat to trim off the hog.
