Chelsea spent a lot of money to reinforce the team of Graham Potter. The squad roster is too large and certainly some sales will take place in the summer transfer market window.
According to what is reported by Daily Mail, AC Milan managers as well as Barcelona and Atlético Madrid are all keeping a close eye on the situation of Pierre-Emerick Aubameyang after being left out of the Champions League squad.
Since Aubameyang was left out of Chelsea's team for the knockout rounds, casting doubt on his future at Stamford Bridge, the Spanish pair and Italian side have all shown interest in possible summer transfers for the player.
Barcelona were keen to sign Aubameyang again in January but they could not do it due to FFP rules. AC Milan and Atlético Madrid were also interested, as per the report. However, FIFA rules prevented the former Chelsea man from joining either side as he could not appear for a third different club this season.
