Chelsea have changed coaches several times but their performances have not improved. Rather, their performance has deteriorated further. Chelsea's performances have been very poor and erratic this season. This clearly shows that the main reason for Chelsea's poor performance is their players. There is probably an internal conflict between the players. This is why they are not playing well. And so changing coaches again and again cannot be a solution. Chelsea needs to change their entire squad. Chelsea's performance is unlikely to improve unless the players change.
I don't think Graham Potter and Lampard are the proper coaches to make Chelsea competitive in the Premier League, but Pochettino will probably be what is needed to do it. At the moment, Chelsea have a lot of quality players who basically just need guidance and a good strategy to get them to give their best performance. So a change of coach is expected to improve the quality and ability of the team, and I don't think they have to change everything.
Chelsea need a good striker, that's true but they have tough midfielders and defenders. Next season will be a different season for them, I'm sure about that. At least I can hope that Chelsea will return to being competitive in the Premier League even if they don't win the title.
Lampard... I think Chelsea should forget about him like a bad dream and never think about him again, because he basically did nothing good for the team, only made it worse in the table. I'm not saying he did it on purpose or anything like that, it's just that after that incident there are doubts about his coaching competence at all
The worst move Chslea had was using Lampard as their coach because they couldn't solve any problem there and instead of helping Chelsea when they hired Lamard and he got bad results with his teams he just lost his reputation.
I also think that Manchester City really shook up Europe this season because it not only won 2 titles in the English competition but also managed to win the prestigious European title, namely the Champions League. Pep Guardiola managed to register his name as the best coach in the world today by successfully bringing two different teams to get a treble winner.
I don't think there will be a coach who will be able to break Pep Guardiola's record in the next 5 to 10 years because with a season that is always competitive every year it will be very difficult for any team to get a treble winner and I am very impressed with what Pep Guardiola has done this season with Manchester City.
Pep is a master of the game so I wasn't surprised to see him snatched the EPL title from. Arsenal towards to closing stages of the league - I mean, he did it to my team (Liverpool) a couple of times so no surprises there. All through the season, they played commanding football and it was clear that they'll end the season in style. Pep has a impressive track record of winning the UCL title with more than two teams. During the CBS interview after the game, he said winning EPL isn't too hard for him anymore.
Currently, Pep Guardiola is the best coach in the world and because of the performance he had I'm sure he can get the reward of being the best coach soon, he is working at Manchester City since 2016 and finally, he won the champions league with this team for the first time in their history.
