You don't need to argue against Sarri to me
But even he was miles better than Pirlo. At least he was a real manager. And we did play some good games with Sarri which never really happened with Pirlo. With Pirlo we were ok at best a few times.
Just out of curiosity, why do you believe we can improve under Pirlo? It's not like he has a winning track record as coach. If anything, we have regressed as the season progressed. Furtrhermore, there is no evidence that he has some brilliant ideas that he needs more time to implement other than the regular "trust the project" from Paratici after every game we look clueless.
