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.
Pochettino must choose his preferred players and those who are not included in his plans for next season they must sell. it will help the club financially for at least one more season to show improvement.
it will be difficult to bring in new players if the club is in a slump, but Chelsea can provide the option of bartering players with agreements with other clubs.
You are right, next season may be difficult for Chelsea, but it could be a big challenge for Pochettino's career. his intelligence and reputation would be used in this situation. One season might be less, but we'll see how it goes. because Chelsea has to see how the big teams stand now not with 1 or 2 years of coaching. they plan for quite a long time to build a team.
