Things might get really interesting if Chelsea bring the right manager for themselves. But there isn't a definition of this in me yet.
They need to make their choice wisely about a manager. I mean that they should be careful about the strategies and tactics of that manager. If they don't match Chelsea then there is no meaning in signing him. I know that they are in a critical time period now so this is exactly why they should be careful with their choices as of now. Their chance against Real Madrid will still not be high though. But if they sign a solid manager then they can at least fight harder in this round against Real Madrid. Nagelsmann seems to be one step ahead now.
Chelsea really have a lot of great players who can build a strong team. But currently the Chelsea team can be said to have completely lost their rhythm. But agree with you, maybe if a new coach is added to the team, the team will regain its strength with new tactics.
I just don't think so, the new coach certainly won't be able to unite the strengths of this team right away, on the contrary, everything takes time and process for the new coach.
in terms of the quality of the players in the Chelsea squad it is very good but with the problems they are facing this season I am very pessimistic that their journey can go further in the UCL this season.
moreover, the opponent they will face is Real Madrid, the king of Europe who has a very good mentality on the UCL stage, I think the chances for Chelsea are very small.
