#2 Lack of match winners
In every successful team, there is not only a talisman but there are many other players as well who pull the team out of trouble when needed.
In Real Madrid, Cristiano Ronaldo was their talisman but they had players like Marcelo, Asensio, Ramos, Benzema and Bale who were capable of winning games on their own as well. Manchester City also have such players in Jesus, Aguero, Sane, Silva and De Bruyne.
But at Chelsea, except for Eden Hazard, we can hardly find a player who can change the game on his own. On some occasions, Alonso and Giroud have been effective, but they are no match winners like Hazard.
We have often seen that when Chelsea are in trouble they always look to Eden Hazard and opposition teams often gang up to stop him. While other players such as Willian and Pedro are not such match winners, and Morata is just another horror story for The Blues.
If Chelsea want to challenge Manchester City, Liverpool and Tottenham they need more match winners like Hazard. Even Liverpool have players like Firmino, Mane, Van Dijk and Struddige, who can step up for Salah and win games for them.
The Stamford Bridge outfit need to sign players like Pulisic and Icardi who can win games or prove to have a major influence on the game from their position.
