And the players who should fill them.
Left Centre Back
Out: Antonio Rüdiger

In the words of Pep Guardiola following Sergio Aguero’s final game for Manchester City; “we cannot replace him”. “Rudi”, as the fans have come to know him as, is a player Chelsea will struggle mightily to replace. His leadership, nuance for the position, and dressing room presence are irreplaceable traits. The German international started 34 out of 38 games for Chelsea in the Premier League last season, en route to earning a place in the PFA Premier League Team of the Year. Regrettably, the club could not come to an agreement with Rudi for a contract extension, so he has since signed for the European Champions; Real Madrid. Finding a centre back who can play in the left of a back three is already a challenge in itself, however, it is not impossible as there are candidates that fit the bill.
In: Joško Gvardiol (RB Leipzig)

The player that Chelsea should make a push for in this summers transfer window is Joško Gvardiol. Pictured below courtesy Fbref is a side by side comparison of Rudiger (left) and Gvardiol (right). Based on the stats provided, it is evident that Gvardiol would be a great replacement for Rudiger. His ball carrying and ball progression skills are in the elite tier for his position. Additionally he is solid on the defensive side of the field, as most of his defending statistics indicate. The one area which could use improvement in his game is ball retention, but for a player that is only 20 years old there is more than enough time for improvement in this area. Some may argue that Levi Colwill should be given a chance to replace Rudi, but he has not yet played in the highest level of European football, which Gvardiol has. Signing Gvardiol would allow for Colwill to go on another loan (potentially in the top division of a top 5 league) and allow for Tuchel to re-assess his performances in anticipation of the 2023-24 season.

Right Centre Back
Out: Andreas Christensen/César Azpilicueta


Some Chelsea fans may feel sick at the thought of Andreas Christensen, but he had his moments of brilliance for the club in the right of a back three. Likewise, César Azpilicueta has been a great second option filling in at the position when called upon. Unfortunately, Christensen also failed to reach an agreement on a contract extension and decided to leave Chelsea to join Barcelona FC on a free transfer. It looks as though “Azpi,” as the fans call him, may follow Christensen to the Catalan club as well. Having captained the club since 2019, Chelsea will miss Azpi’s leadership skills. The impact he had in the three years he served as club captain was invaluable to the clubs success in that time. Replacing both players will be a tall order for the club, yet there are candidates that can possibly fill the void.
In: Jules Koundé (Sevilla FC)

The ideal player to fill in at right centre back is Jules Koundé. He is a player that the club has scouted for a while and he almost signed for the club in last summers transfer window. He can play at both right centre back and right back, which is the type of hybrid player Chelsea coach, Thomas Tuchel, admires. Pictured below is a side by side comparison of Christensen (left) and Koundé (right) courtesy of Fbref. Based on the statistics shown, Koundé’s main strengths are retaining the ball and progressing it from central defence. This is crucially important to how Tuchel’s Chelsea advances the ball (also pictured below courtesy the Athletic). He does not come without flaws however, as there is work to be done on his defensive game. Still, at 23 years of age there is time on the Frenchman’s side to improve in those areas. Signing Koundé will also give Trevoh Chalobah competition for the right centre back position, which should bring out the best in both players.

Centre Forward
Out: Romelu Lukaku

Another player which Chelsea fans may feel sick at the thought of is Romelu Lukaku. His £97.5 million transfer from Inter Milan last summer has been nothing short of a disaster and it is best for both parties if an agreement is made to part ways. In finding a replacement for Lukaku, the club should avoid the mistake of identifying a striker with a similar profile to the Belgian international. Any target that the club picks out must have the ability to score goals, create for his teammates, and show a willingness to press the opposition defence when not in possession of the ball.

In: Evanilson (FC Porto)
It seems as though every big money move Chelsea has made for a centre forward in recent history has failed, so the club should try a different approach. Evanilson is a player that should not command a heavy transfer fee yet he would fit the profile of a striker that would find success in Tuchel’s system. The 22 year old Brazilian centre forward plays for FC Porto in the Portuguese first division and he had somewhat of a breakthrough this season. He contributed 14 goals and 4 assists in 25 Liga Portugal starts, but he has gone under the radar due to being overshadowed by the other stars in this Porto team such as: Luis Diaz (who signed for Liverpool in the January transfer window), Vitinha, and Mehdi Taremi. The table (shown below courtesy FBref) is a comparison of Evanilson and Lukaku’s per 90 minutes stats in their respective domestic leagues last season. From the data presented, we can see that Evanilson is an above average goal scorer, averaging 0.62 goals and 0.18 assists per 90 minutes. Furthermore he averaged 0.80 combined goals and assists, which was almost double that of Lukaku (0.45). The area where he truly excels in, however, Is his work off the ball. In the graphic shown below (courtesy the Athletic) we can see that his defensive contribution is exceptional.
