This summer is the craziest transfer window ever, and many major deals were completed on the transfer window deadline. Famous reporter Romano revealed some details of the transaction, including Chelsea's attempt to introduce Fermin and Hader.
In this summer's transfer window, Chelsea has never been close to introducing Felmin. Chelsea offered Felmin 40 million euros, and they wanted to see if the players and Barcelona were interested in the deal before considering whether to complete the deal several hours before the transfer window closed. That's what the Blues stand for. Fermin is not a player that Chelsea must sign, they just regard it as a player that can be considered in the future.
After Drapp was injured, Chelsea asked about Hader's situation, but the player himself would rather join Leipzig than Chelsea and Milan. Because, he feels that he can get a stable playing time in Leipzig. As a young player, he wants to make progress and get playing time instead of sitting on the bench at Chelsea or Milan.
