Seems very weird thing to happen. Perhaps the Mafia are involved? Does not sound like an attempted suicide, as would have jumped from a higher distance, and why would you jump through a window? Would have been easier and more practical from the roof. And why at Juve HQ, would it not have been easier from some bridge or any other building? At least then, no-one would see you.
Pessotto is one of the nicest guys I have ever met, and he is a very intelligent and popular guy. NOT attempted suicide, it must be somehow connected to the Mafia, or even Moggi. No proof yet, but it will come soon. This act signals the start.
Get well soon Pessotto!
