Thomas Tuchel changed Chelsea's fortunes in just a couple of months. In January, the Blues were lacking results and seemed lost - until they appointed the German coach. Those days seem far behind them, as they claimed the UEFA Champions League title and seem to be one of the main contenders for the Premier League crown this season.

But far from being satisfied with their continental glory a few months ago, expectations at Stamford Bridge are even higher for 2021-2022 and there's not room for anyone in the squad. That's why they offloaded Tammy Abraham and Fikayo Tomori, among others.

Chelsea, meanwhile, completed the return of Belgian superstar Romelu Lukaku to give a huge upgrade to their attack, and they wouldn't stop there. According to Fabrizio Romano, the Blues could go back into the transfer market to sign these two players:

Jules Kounde

Tuchel would welcome the arrival of a dependable center-back to have more depth and competition for the starting role. Sevilla center-back Jules Kounde seems to be Chelsea's target for the defense.

At 22 years of age, the Frenchman has a bright future ahead of him and that's why the Blues would be eager to land him. According to Transfermarkt, his market value is $66 million, so the English side might need to spend a huge fee again.

Saul Niguez

The Spanish midfielder has been linked with a move away from Atletico Madrid over the summer, with the likes of Manchester United and Liverpool heavily linked with him.

But now it might be Chelsea who set their sights on Saul Niguez, whom the Colchoneros would be open to selling. In the meantime, he has started for Diego Simeone's side in La Liga opener against Celta.
