Barcelona's pre-season preparations have been disrupted by a serious injury concern, with Frenkie de Jong confirmed to have suffered a tear in the medial collateral ligament of his right knee. The Dutch midfielder revealed he played through pain during the World Cup, making the diagnosis a significant blow as Hansi Flick's squad begins to take shape for the new campaign.

On the transfer front, the club has moved quickly to reinforce the attack. Karim Adeyemi has joined from Borussia Dortmund on a five-year deal for a reported €29 million, becoming the second high-profile arrival of the summer after Anthony Gordon. The Germany international arrives to fill the void left by Robert Lewandowski's departure and the end of Marcus Rashford's loan, and has already spoken about his ambitions for Champions League glory alongside Lamine Yamal.

The squad picture remains incomplete, though. Barcelona are waiting on Julian Alvarez to force his exit from Atletico Madrid, with president Joan Laporta making clear that the club's offer carries a deadline. At the same time, Ferran Torres looks increasingly likely to leave after rejecting the club's contract renewal terms, with PSG positioned to sign him. Barcelona have also been linked with Aymeric Laporte as a low-cost defensive option following his World Cup performances with Spain. The combination of De Jong's injury, ongoing outgoings, and unresolved transfer targets means Flick still has considerable work to do before the season begins.
