Chelsea as a club needs someone that knows what he is doing,there are so many coaches who have managed Chelsea,but didn't succeed because the way at which the owner of the club handled things in that club is not really proper.I will still say it again,that Chelsea can never get a coach like the man that gave them Champions league trophy.Chelsea wouldn't have been suffering the way they are suffering now if that coach was still their head coach,but because he has been sacked,and there is no coach that can take on the work at Chelsea just like that man did,they will continue to suffer.
When a club is doing well,it's simply because the coach there is teaching them well.Its always as a result of good and bad coach.
chelsea is actually one of the popular teams in the EPL that used to have its glory days when it had a great season but all of that is no longer there all of it has disappeared after not being able to get the right coach as well as management that may not be able to manage the team back to its glory days and I admit that for several seasons there has not been the right coach who is able to handle Chelsea to improve their performance and return to their glory days, but unfortunately the management always changes coaches when they fail to get a title and it is a very bad mistake to bring in expensive players without quality talent so it is just a waste money without getting good achievements.
this is Pochettino responsibility as a coach he was given the responsibility to handle this problem but instead he chose players who were not qualified but whose prices were very unreasonable and now there is nothing that can be done because Pochettino has to be responsible for all of this.
one of the ways Chelsea can revive its performance and regain its glory days is that the management must be able to bring in experienced coaches such as those currently coaching several top teams and must retain them for several seasons to give these coaches the opportunity to have a way to achieve higher titles.
