Here's what the club should do in the current situation:
1. Fire Sarri today. The players will be relieved, happy and motivated. The Elite Premium Anti-Sarri Tuz Club will be happy as well.
2. Re-hire Sarri tomorrow. The players will be angry, and this anger multiplied by their yesterday's happiness and motivation will make them unstoppable, and they will win the scudetto and the CL simply out of spite. The Not That Elite Non-Premium Pro-Sarri Tuz Club will be happy to have Sarri back. The management will show their maturity: what idiots would fire their coach 5 rounds before the end of the season? So, the people will have facts to prove the point that the management is mature, prudent, wise, and can quickly learn from their mistakes.
3. Having won the scudetto and the CL, fire Sarri again and dismiss half of the squad. After that ask Mark to move all of them, including Sarri, to the Legends section on Tuz, to diverge the people's attention from the fact that Nedved and Paratici are still running the club. Re-hire Allegri and replace the dismissed half of the squad with a group of exquisitely non-technical players according to Max's typical requests, and let him dominate Europe for the next five years.
