Andreas Christensen could soon be leaving Chelsea Football Club. The centre-back has been one of the Blues' better defenders over the past year but his contract is set to run out in the summer. Barcelona are also closing in on a free deal for the Danish defender.Chelsea need to make plans to replace Andreas Christensen in the summer transfer window View this post on Instagram Instagram PostAll of the Blues' trophies under Thomas Tuchel have come on the back of an incredible and extremely frugal defense. But they could lose three defenders in the summer. Cesar Azpilicueta and Antonio Rudiger have their respective contracts expiring in the summer as well. But the loss of Christensen will hurt Chelsea the most, given he is still 25. However, since he is nearing a departure, the West London club will have to line up replacements. On that note, let's take a look at five players who could replace Christensen at Chelsea.#5 Matthias GinterHannover 96 v Borussia Mönchengladbach - DFB Cup: Round of SixteenMatthias Ginter is one of the most well-rounded centre-backs in world football at the moment. Borussia Monchengladbach may not be performing well in the Bundesliga this season, but Ginter has continued to shine.Fabrizio Romano@FabrizioRomanoMatthias Ginter announces he’s gonna leave Borussia Mönchengladbach as free agent in June: “I’m not extending the contract with Borussia. I’ll start a new chapter in my career, the decision has been made”. #BMG2:35 AM · Dec 29, 202117325872Matthias Ginter announces he’s gonna leave Borussia Mönchengladbach as free agent in June: “I’m not extending the contract with Borussia. I’ll start a new chapter in my career, the decision has been made”. 🇩🇪 #BMGThe German club's defensive record is one of the worst in the Bundesliga but very little of that can be put on Ginter. The German international has been solid against some of the league's best strikers and has been composed in passing the ball out from the back as well. He is a solid defender with and without possession of the ball. Moreover, his stature and style of play are similar to that of Christensen, with both extremely calm players even in high pressure games.Another aspect both players share is that Ginter, too, shall be out of contract in the summer. He has already announced his decision to leave the club and Chelsea could sign him on a free transfer once Christensen leaves permanently.#4 Trevoh ChalobahChelsea v Crystal Palace - Premier LeagueTrevoh Chalobah has quickly become one of the go-to centre-backs for Thomas Tuchel. Following a couple of loan moves, the Chelsea academy graduate broke into the senior team this season.Chelsea Loan Army@CFCLoanArmy_Trevoh Chalobah:"Last year I was at Lorient on loan. Now I could win my 3rd trophy at Chelsea.”"Going on loan 3 times, you could easily think, ‘I’m never going to get to where I want to be’. I kept going & I want to be an example for younger boys coming up.[ @AdamNewson ]5:41 AM · Feb 25, 20223559198Trevoh Chalobah:"Last year I was at Lorient on loan.

I kept going & I want to be an example for younger boys coming up.[ @AdamNewson ] https://t.co/477deNE6h9He kept a clean sheet and scored a goal on his Premier League debut and has not looked back since. The Englishman is young and fast and also has an incredible positional sense, which helps him come out better in one-on-one situations. Chalobah is already looking like the real deal and has played more league games (15) for Chelsea than Christensen (14) this season. A perfect like-for-like replacement, Chalobah could easily replace Christensen at Stamford Bridge next season.
