Barcelona's summer is being shaped as much by injury news as by transfer activity. Frenkie de Jong has been diagnosed with a medial collateral ligament tear in his right knee, a serious setback that clouds the club's midfield options heading into the new season. The Netherlands international revealed he played through pain during the World Cup, making the diagnosis all the more concerning for Hansi Flick's squad planning.

On the transfer front, the club has moved quickly to bolster its attack. Karim Adeyemi arrived from Borussia Dortmund for a reported €29 million, signing a five-year deal and becoming the second high-profile summer addition after Anthony Gordon. The German winger has already spoken about targeting Champions League glory alongside Lamine Yamal, whose own status as one of football's elite was underlined when his rookie trading card sold at auction for $707,600, surpassing memorabilia records held by Lionel Messi and Pelé.

The pursuit of Julian Alvarez from Atletico Madrid remains the dominant transfer story. President Joan Laporta has made clear the club's offer will not remain open indefinitely, and Barcelona are already identifying alternatives, with Bournemouth's Eli Junior Kroupi emerging as a backup option. Ferran Torres, meanwhile, appears increasingly likely to leave, with PSG holding a concrete offer on the table after the forward rejected Barcelona's renewal terms. A friendly win over CE Europa, 4-1, provided a positive pre-season note, with a trip to face Birmingham City next on the schedule.
