I don't understand why don't these teams like Roma and Napoli learn from past experiences. They put immense pressure on themselves and that's why they implode.
When the CL referees made those mistakes on Bayern-Juve, the Italian media and the Juve fans went berserk, but the manager and the Juve people shrugged it off with some "I don't want to comment the refereeing" statements. They did it because they knew the result vs Bayern won't change if we complain, but we still have a scudetto race to run and we can't put more pressure on our players. Pressure makes players loose their coolness and it leads to mistakes.
But Napoli and Roma do the opposite. Instead of avoiding it, they seem to be waiting for something controversial to happen.
It looks like they were hardly waiting for a pro-Juve mistake to happen, and when it finally happened after 30 rounds, Sarri and his players lost it. Today's mistakes and the implosion is a result of their reactions after Torino-Juve. Not only that they were struggling to handle the pressure, but they somehow managed to multiply it.
