Chelsea's problem is bigger than a change of coaches; the team lacks a game plan and must focus on signing multiple prospective players during the transfer window if they are to start winning games next season.
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.
Chelsea's problem is not a problem of the coach. It is beyond a problem of coach , I think there are things that are supposed to be work on for the team to become strong again. Chelsea needs to examine what really the problem could that have been affecting them and if they work towards it I'm sure things is not going to remain the same. If you keep on doing the same thing all over just expect the same results, Chelsea have been doing the same thing for awhile now that is why they keep on having the same challenge. This is time the right things are suppose to be done to be in that best form.
