Barcelona suffers a major blow in the title race against Real Madrid.

Barcelona continues to face unfavorable updates on their personnel, with Jules Kounde having to leave the field prematurely during the high-stakes clash with Atletico Madrid, coinciding with the La Liga championship battle entering a critical phase.

The French defender, a key pillar in coach Hansi Flick's backline this season, played only 11 minutes in the Copa del Rey semi-final before exiting due to a muscular issue.

The incident occurred during a defensive retreat on the right flank. Kounde suddenly collapsed on the pitch, clutching his right calf with a look of deep disappointment. Recognizing the severity, Hansi Flick immediately instructed Alejandro Balde to warm up. Barcelona's medical team, led by doctor Ricard Pruna, quickly attended to him, but the decision was made almost instantly: Kounde could not continue playing.

Losing Kounde forced Hansi Flick to immediately alter the defensive structure. Joao Cancelo, who started the match as the left-back, was shifted to his preferred right-back position to fill the void. Balde came on to take charge of the left flank.

Although Balde provided speed and attacking support, he could not offer the same solidity in transitional situations as Kounde. Before the match could settle into a rhythm, the tactical discipline Flick emphasized pre-game was put to a real test.

Barcelona's medical department will conduct further in-depth examinations to determine the exact extent of the injury to Kounde's calf. However, initial signs suggest he may be sidelined for a period, joining the long list of players currently undergoing treatment for injuries.

Kounde is the newest addition to Barcelona's "injury ward." For the match against Atletico, the Catalan club was already missing Eric Garcia due to suspension, while Gavi and Andreas Christensen remain unavailable.

Coach Flick is also having to manage without the absence of Frenkie de Jong and star striker Robert Lewandowski. The Polish forward is nearing a return, but if he plays against Athletic Bilbao this weekend, he will have to wear a protective mask due to a facial injury sustained in the match against Villarreal.

The series of injuries to key players is putting significant pressure on Barcelona's squad depth. With a congested schedule in La Liga and European competitions, Flick is undoubtedly hoping for positive news regarding Kounde's condition.

For now, Barcelona must focus on the title race. After concluding their Copa del Rey fixture, the Blaugrana will turn their attention to an away trip to face Athletic Bilbao in La Liga. Barcelona currently leads the table with 64 points, holding a 4-point advantage over Real Madrid, and is determined to maintain this lead as the season enters its decisive phase.
