"Monza is the place to announce the Scuderia's next year's combination of drivers"
This myth is really one of the most persist ones, but reality shows the opposite: It was probably only two times in the Scuderia's Formula 1-History that the team announced the combination of drivers for the following seasons at their homeland Grand Prix.

Btw., the Scuderia points out that Monza and Singapore are the key GPs to decide to battle on for the championship or to focus on 2014.
