Barcelona forward Dani Olmo has been ruled out for four to five weeks due to a right hamstring injury sustained during a match against Girona, where he scored before being substituted. The injury presents a significant challenge for manager Hansi Flick as the team prepares for their Champions League opener against AS Monaco on Thursday. Olmo, who joined Barcelona from RB Leipzig for €55 million, had made an impressive start to his career at the club, scoring in all three of his appearances, a feat not achieved by a new player since 2011. He will miss several upcoming matches, including La Liga encounters against Villarreal, Getafe, Osasuna, and Alavés. The injury comes as Barcelona enjoys a perfect start to the La Liga season, having won all five matches so far. The team hopes to maintain its momentum despite this setback.
