It's not about their squad, it is about management. Chelsea poor performance last season was not as a result of squad, it was how Pottechino was making use of the wrong players in the wrong position. If we want to talk about squad, Chelsea is not the club with the weakest squad in the Premier league but their couch failed to utilize them very well. If Enzo will make use of different approach and use the players accordingly and where they are best good at, Chelsea will definitely make a different season better than what they showcase last season. Towards the end of last season, we all saw how their game pattern changed when Pottechino started using the appropriate players combination.
That has been talked about a lot and yet some people still insist that Pochettino was a great manager before, so why would he be bad at Chelsea. It's simply sometimes misfit, not every manager could fit perfectly for every team, while they can be great at one team, they can be terrible at some other team, it's as simple as that.
We should be looking into what people will do, and how they will react, and keep them or fire them based on that. Pochettino was great before so they hired him based on that, but used the players terribly so he was fired because of it. I think this season they will be a bit better, not some amazing great manager now, still a bit question mark, but a change will do them some good in the end for a better future.
