That is according to former Liverpool and England centre-back Jamie Carragher.
Carragher was speaking at half time of Chelsea’s visit to Manchester City on Sunday.
City raced into a 4-0 lead at the Etihad after just 25 minutes of action, with Sergio Aguero netting twice.
The Argentine scored his third after the break to make it back-to-back hat-tricks at the Etihad.
Speaking at half time, Carragher claimed Chelsea’s performance was as bad as recent defeats at Arsenal and Bournemouth.
And he says it reminded him of the Gunners playing away from home in the last few years.
“City outstanding,” Carragher said on Sky Sports.
“I called a couple of Chelsea performances a disgrace going into this game – this is as bad as anything.
“Looking at Sarri, he’s obviously only just over halfway through his first season, but the worst thing I could say is it looks like he’s turned Chelsea into Arsenal.
“That Arsenal team that used to get battered for the last seven or eight years away from home in big games because they were too weak.
“You could never say that about Chelsea, no matter what’s gone on, that they were weak.
“We are watching a really weak football team here. He’s saying he can’t actually motivate some of the players.
“This is criminal from [Marcos] Alonso. Look at this, so casual three or four minutes into a big away game.
“You do not leave your post until [Eden] Hazard is back with him.
“And players with the quality of [Kevin] De Bruyne, [David] Silva, are switched on, alive.
“They were not switched on at all.”
