In general it is logical that the root of all problems in Todd Boehly. Here it should be noted that he apparently adheres to the American position and in sports that money can solve almost everything. So apparently after the Potter debacle he decided to make a big purchase for Chelsea so that star players could fix the situation, but things as we understand it turned out differently.
Now Poccetino will have to rectify the situation, I think he will figure out who is superfluous in the team and probably many of the latest Chelsea purchases will be put up for sale or on loan, I think that by 90 percent will remain Enzo Fernandez and Mudrik, because he seems to have such a clause in the contract, and the other potential players for the transition.
But the real problem is that the harm is already done and can't be fixed within a single year. Not playing the Champions League is a massive drawback for the team and the club. First of all they need to get rid of any players who underperformed last season unless Pochettino thinks he can get them going again, but at the same time they need to keep their squad together. But when they don't participate in the Champions League it will be hard to convince new players to go to Chelsea. Boehly went literally crazy with all those transfers and now they have a ton of players and nobody really knows what to do with all those guys. He also expected that it would work out and now I wouldn't be surprised if there are also issues financially that limit their ability to bring in some other guys. This will be a rough year for Chelsea.
