Give him time.it took Alegri half a year to implement his ideas and made us great on wards.
Sarri is trying something new that this club never experienced before.
He has to change our style and get results in the same time.and I think He is doing a very good job until now , our team was hugely Costa dependent at beginning of the season , but now we are creating chances easily without him on the pitch.
Team is improving with each game passing and this is the most important thing right now.
First, it was we had no plans, we fired Allegri and hired Sarri all in a panic (mind you these fans followed the club for the past 8 yrs) before Sarri said he had never seen a club so well-planned & detail-oriented in their approach before.
Then, it was he won't rotate or play another formation or be willing to change anything.
Now, it's "we only won 2-0, not 4-0, worried."

With Allegri it was different as he used the basis of Conte's ideas and over time evolved it to something better. With Sarri it is a complete overhaul of the old style, thus it will take longer. Tbh we've handled it pretty well so far when you compare it to say Milan who are trying something similar, but unlike milan at least you can see some of the ideas coming through.
This is ridiculous level of good logic. It was all supposed to happen and get implemented before the first game.
