Chelsea are going about it the wrong way. You don't build a team in just one season. I still don't get how they didn't learn from their mistakes the first time. You can't buy a bunch of potential players and expect them to be perfect together. A team is built with time.
When Boehly first took over, he should have made 5 signings at most. Out of those five 3 should have been world-class players why 2 can be potential players. Then the next season they can make 3 or 4 more signings, both world-class and young potential players. Also, they should be recruiting for their youth and teenage team too.
If they have done that, they'll have made 8-9 signings in the past 2 seasons and this season they'll just be looking for more players to strengthen their squad.
This way you'll find out that in 2 years they have filled up every area on the pitch with quality players and still have quality squad depth on the bench.
Right now, Chelsea is in a confused state and they're just signing different young players. Most of those young players are like shitoins, they won't turn out to be anything, Over a billion pounds spent yet they still don't have a world-class squad, that's pitiful.
Why all these? You talk about Chelsea and you forget that both the owner and the fans are desperate set of people, they can't learn until they are close to the relegation zone without escape. When trying to build a strong team it takes time, that you are right but in this CFC they want it to be done as soon as the season begins, that's bad and unhealthy for a club like Chelsea. Past glory is all they see nothing more and I feel bad when such a team always miss out in the UCL each season.
Todd Boehly saw Chelsea football club as a business ground where whenever he blinks money pours out of nowhere, the down fall of Chelsea started when the current owner talking about Todd Boehly sacked all the staff that was working very hard to make things be in a good shape and now he doesn't know how to correct those mistakes, getting the right people to work with is the problem instead he's running around signing players that can't make the team stronger.
