Chelsea's decline is difficult to understand, although many say they are too young and inexperienced but I don't think that's the right reason. I suspect there are other problems that might cause the Blues' performance to plummet. Conditions in the dressing room or perhaps less harmonious management could be the main cause. There was news in several media that stated that Bruno Saltor and Claude Makalele had also left, maybe there was something wrong even though it didn't come out to the public. I think Boehly must immediately improve the non-technical side so that Chelsea's condition returns to stability.
Apart from the factors as mentioned which made Chelsea experience setbacks. I look at Chelsea now, I understand that as the new owner, Boehly wants a major revolution by overhauling the existing squad. The only thing I regret is, in the transition era it was not done gradually but immediately 'throw away' all the players from the Abramovic era without first retaining the pillar players as the framework of the team.
Maybe another factor was the purchase of players who were in a hurry, eager, all of them were bought and most of them were young players. As usual, if young players are not guided by senior players in their team, they will have difficulty developing because of their egos, and this has also been said by Frank Lampard before, that Chelsea players find it difficult to unite and there is a lack of solidarity in a team.
