Yeah. It does look like Sarri is very reluctant to change. So early in his managerial time at Chelsea and he is already saying I'm not changing, you all have to change. From the outside looking in, it does seem like he is doing what Mourinho sort of did with us this season. I mean, he has a lot of good players at Chelsea, probably some of them better than what he had at Napoli, but he want them to be his old team and they are not. Fine they have some trouble but I don't understand why he wont try to change a few things at least, that has to be worrying.
It's making him look like a terrible, inflexible coach if he has no yield or contingency whatsoever. Especially so when he's not getting the best out of a single player at his disposal.
It's easy to pile on Jorginho all season because the same things will keep happening, perhaps even worse as his last dribs of confidence erode, but he's not the one to be pointing the finger at if nothing in the system being played is adjusted.
What are those optimal conditions ? At the moment Jorginho is trying to play like he did at Napoli but it's not working because the Chelsea team isn't built for that alright but his individual performance stinks so much that you have to wonder how good he was to begin with. It'll be hard for me to be convinced that Jorginho wasn't being carried. He cannot keep the ball when pressed, cannot create any good openings with his passing never mind goalscoring chances.
Napoli were a well-oiled machine with so much synergy players knew what to do and when to do it automatically, further, Jorginho and his game, flaws inclusive, was completely catered to and for. All of that has been stripped away, and then you're left with a 'every man for himself ' midfield, which is a slow, immobile and not particularly adroit players' idea of death by a thousand cuts, especially so in England, and even more so when he is being relentlessly targeted.
Sarri is doing everything in his power to destabilise his players and Jorginho, being a terrible athlete as well as poor positionally, is ironically suffering the most of all the players under a manager who brought him to the club in the first place!
Even under optimal conditions being a pure DLP in the PL would be a challenge; under these conditions it's the same as throwing him to the proverbial lions.
