3 things Chelsea need to do to become one of the strongest teams in Europe

#3 Buy a new centre-back, right winger and striker

Olivier Giroud: Chelsea's first striker at the moment

Sarri's squad looks very good. However, there are several positions in his squad that require reinforcements. So, Chelsea need to buy some world class players to strengthen their squad. In my opionion, these are Chelsea's weekest positions: centre-back, right-wing and centre-forward.

Antonio Rudiger is by far The Blues's best defender. Currently, David Luiz is his partner but Chelsea should look for a new partner for Rudiger.

On the right side of his attack, Sarri likes to have a player who is capable of making the runs into space. Pedro Rodriguez is a perfect player for that job. Because of his age, Chelsea should find an effective backup option.

And finally, a new striker should be their priority number one in the upcoming transfer windows. Alvaro Morata and Olivier Giroud aren't the best options for the future and the board should look for a striker that can fit into Sarri's system.
