Chelsea are among the clubs interested in RB Leipzig star Christopher Nkunku, who won the Bundesliga Player of the Year.
The 24-year-old is currently in contract negotiations with the DFB-Pokal winners but the Blues believe they are able to disrupt the discussions and take advantage.
Real Madrid are also monitoring the situation, although are reportedly prioritising the signing of Monaco midfielder Aurelien Tchouameni.
They need to sell first with limited minutes given to players like Pulisic, Timo Werner and Hakim Ziyech this campaign leaving them frustrated.
Romelu Lukaku hasn’t hit the heights that many expected despite him ending the campaign as the club’s top scorer on 15 goals.
The problem is all four forwards are expensive for interested clubs when transfer fees and wages are considered, leaving only big English sides and top Champions League sides able to buy them.
Borussia Dortmund are reportedly interested in signing Werner but appear to have gone cold on a deal over cost. Currently, the Germany international is Chelsea’s fourth-highest paid player on around £275,000-per-week.
The Blues are able to cash in on Armando Broja, who is a major asset targeted by clubs like West Ham, Newcastle, Southampton, Inter, AC Milan and Napoli.
The 20-year-old is seen as an exciting prospect and £25m could start the conversation over a possible transfer. However, Thomas Tuchel is wanting to see the Albania international in pre-season before making such a decision.
The priority is clear and it is to sign a defender. Jules Kounde is the main target with Sevilla open to selling him for the right price and Chelsea having already turned the defender’s head with personal terms agreed.
“We will have the chance to act and make up, because the disadvantage in terms of timing for the rebuild is big,” Tuchel said after the final game of the season.
“We have to be fast and smart. The disadvantage grows every day, of course, while the two top teams [Liverpool and Man City] improve their teams, and have very clear teams on which they build.
“It’s a kind of rebuild for us and makes things even more challenging.”
