Chelsea made "big" transfers last season and looking to get out of that now. They have tried "inject a lot of money quickly and find a way to win" but they have failed that so I think it is going to be tough to do the same thing.
So, instead they are selling the players they have, and getting younger players and hoping that it would work for them in the end. I am not saying that it would be a smart decision or anything like that, I am not saying this is what they should do, all I am stating right now is the current situation. Get rid of superstars that worth a lot of money, and use that money to get young players with some potential and that would be a good thing for the future. I believe it is actually a good idea for sure.
Chelsea spent a lot of money last season on signing new players, but they failed to perform well in the league. As for me, it is from the coach, as they have recently hired a new coach.The manager's job is to find players that fit into his style of play and trust him as a mentor. He must select his own players. It's what Guardiola has done for City, and those players will always go above and beyond for him. I believe Chelsea will play great ball next season, and they will perform very well under the new manager. Chelsea will be a difficult club to beat next season.
