RB Leipzig are navigating one of the most turbulent summers in their history, defined by a record-breaking sale and a striking failure in the transfer market. The confirmed departure of Yan Diomande to Real Madrid for a base fee of €125 million, rising to a potential €140 million with bonuses, represents the club's biggest ever sale and equals the third-largest transfer in Bundesliga history. The 19-year-old winger scored 13 goals and contributed 10 assists in 36 appearances last season, and Leipzig held firm against offers of around €100 million from Liverpool and others before Real Madrid met their valuation. The windfall hands new head coach Martin Demichelis significant resources to reshape the squad, but it also strips him of his most electric attacking weapon ahead of the new Bundesliga campaign.

The club's attempts to address that loss in attack then suffered a serious blow. A deal to sign Hoffenheim striker Fisnik Asllani, reportedly agreed in full with a five-year contract ready to sign, fell apart at the final stage after Leipzig raised medical concerns during his physical examination. Hoffenheim confirmed the transfer would not proceed, insisting Asllani is fully fit and will return to training. It leaves Leipzig without their primary striking target just days before the new season begins.

Further uncertainty surrounds Antonio Nusa, with reports linking the Norwegian winger with a €60 million move to AS Roma. Losing both Diomande and Nusa would leave Demichelis severely short of wide options. Leipzig face Leeds United in a friendly on Saturday before the Bundesliga season gets under way.
