Napoli will lose at least two key players in the summer or more, so they have their chance to make history now before those around them close the gap. Also, I'm sure Inter would take him back without any questions asked if the opportunity presented itself.
All things considered, if he wants to continue in club management, he will need to learn to hold his tongue sooner rather than later.
