Yes, Chelsea's problem is really complex. Many people blame the coach. It's true, coaches are responsible for the performance of their players. But if you look at it here, even when they changed with a new coach who shone at the previous club, in the end they couldn't bring about change at Chelsea. This is because the problem is complex. And it's true, signing too many new players at once, and playing them right away, and even though most of them are not players who are very good at implementing tactics. Why didn't Chelsea make the decision to sign fewer players but those who could really contribute quite strongly to the club, so that at least the squad had target points that could be relied on in every line, especially the front lines for goal-scoring executors. Hopefully next season Chelsea can change more, it's a pity they didn't enter the UCL.
