The thing that I notice that is cussing the problem of Chelsea is the coach because the arrangement or the lining of players cannot contribute the feet from Chelsea club, another thing that I found out with that of Chelsea to start winning or defeating their counterpart is for the management of the club to change coach and and buy more players.
Chelsea already has a large number of new players, therefore adding more players is not necessary given the quality of the players they already have on the squad.
Chelsea needs a new coach, as you have already indicated. Although fans have been calling for a new coach for a while now, I still don't understand why they haven't yet followed that.
By the start of next season, am anticipating that all of Chelsea's new players will align with one another on the field of play.
