While the team have done their best to avoid confirming that they have parted ways with the popular Italian, the story doing the rounds of the paddock is that his dismissal was ordered by the big kahunas at Red Bull after Toro Rosso's disappointing season.
What Toro Rosso need is an aerodynamics specialist.
And - according to what an unnamed but very reliable source just told me - that specialist is ex-Sauber technical director James Key, who has been on gardening leave since just before the pre-season test in Jerez.
Assuming Key's leave was the standard nine months, that should see an announcement at the end of the season. But these contracts can be renegotiated if there's enough money involved, so keep your eyes peeled for a Key to Toro Rosso announcement.
And when you do see it, remember you read it here first, m'kay?
