Barcelona's unbeaten start to the season is over, and the manner of its ending has left the club navigating a difficult few weeks. PSG beat them 4-2 in the Champions League at the Parc des Princes on Tuesday, ending an 11-game winning streak and handing Hansi Flick's side their first defeat across all competitions this season. The result was a genuine test of where Barcelona stand against Europe's best, and PSG passed it convincingly.

The injury fallout from that match has made the situation considerably more complicated. Dani Olmo, who made his 100th appearance for the club on the night, suffered a left adductor injury and has been ruled out for approximately one month. That absence covers El Clasico against Real Madrid on Sunday, as well as La Liga fixtures against Alaves, Atletico Madrid, and Villarreal, and a European tie with Aston Villa. Losing a player of Olmo's technical quality and versatility at this stage is a significant blow to Flick's options.

Despite that, Barcelona's domestic position remains strong. They lead La Liga with 27 points from nine matches, five clear of Atletico Madrid in second. Captain Raphinha has publicly dismissed any suggestion that the PSG defeat will affect the squad's mentality ahead of Sunday's Clasico at Spotify Camp Nou. The challenge now is to absorb the setback, manage the injury list, and refocus quickly for a fixture that will define the tone of their season at home.
