I don’t see Chelsea improving in the next season, to be honest. I would much further put my money on Liverpool. Because I believe if Liverpool can get a really good striker in the team, they will be able to fix most of their problems.
But we cannot say the same for Chelsea. Chelsea will have to make big changes in the team and also get a good manager. It’s really good manager can fix the problems that Chelsea has right now. But even then it will take a lot of time. Chelsea will have to spend a lot of money. I hope they are ready to do that in the next season.
Since there is no big change in Chelsea squad, I also doubt that Chelsea will have a better performance in the next season. Chelsea needs to rebuild their attacking line if they are serious to improve their performance. So far, Cheslea can't sign a top striker, they are only rumored to sign a top striker. The current strikers of Chelsea are not really productive, they rarely scored during the last season.
Liverpool seems a bit better, they still have a good squad although they failed to perform at their best in the last season. If Liverpool can sign a top striker in the current transfer window, they surely may have a chance to perform well in the next season. Well, they have enough wingers, but they only have Nunez in the CF position. So, I agree that they need a CF (striker) now.
