Up until the Lecce game I thought we created a lot of chances and it was just a matter of poor finishing. After that draw no doubt Sarri has been playing it safe, and it really shows. He made radical changes in the beginning of his Empoli and Napoli tenures and struggled initially. Here he cannot afford that and it explains the continuation of Allegri's midfield; the fear of losing points to Conte.
I like Sarri but really disappointed with the 4-3-1-2. Clearly our best football until now was played with 4-3-3, with the exception of the Inter game were the 4-3-1-2 actually worked. Costa has to play wide and not central. Ronaldo has not been effective at all with the new system, so I didn't understand his statement that this formation would benefit him. He either has to use the international break to improve the 4-3-1-2 and if it still doesn't work just scrap it. He doesn't have time to be stubborn in Juve, this is a different animal from his previous clubs. I believe he'll adjust as his post game comments pointed out the issues we're discussing.
