Chelsea had a big difficulty even in keeping a 3-0 advantage against Luton previously. They are really in a bad condition this season but they will just do whatever they can for the rest of the season. There is a big management issues at this team but it isn't because of Pochettino for sure. Before he came the team weren't much different.
Boehly isn't good at doing his work in my opinion. This team deserve a much better owner such as Abramovich. You know how Abramovich's times were. Chelsea were in much better condition than this.
This problem comes from the internal team not from management imo, Todd Boehly has done its best by providing an unlimited budget to build new squad this is the same way done by Manchester City a few years ago and they managed to do it. I personally think the problem is that this coach has not been able to build a cohesiveness in the team in attack lines and defense lines, the defense is the worst because it has not been able to prepare a solid defense while the attack line is a little better it's just not consistent. One thing that can change and improve Chelsea's performance is time I mean they need more time to prepare everything to be better, maybe 1-2 more seasons. We know that Pochettino has the ability to do it, it's just that it needs a process.
You certainly remember how Chelsea brought some great players like Lukaku, Enzo Fernández and more but these players cannot contribute fully to the team while in other teams these players can be relied upon this means that something is missing in Chelsea why re these players less aggressive when playing at Chelsea.
