FC Barcelona suffered a disappointing 3-0 defeat to AS Monaco in the Joan Gamper Trophy, marking the first time they have lost this trophy in 12 years. The match, held at Montjuic Stadium, saw Barcelona fail to capitalize on early chances, with Raphinha's goal ruled offside before halftime. In the second half, defensive errors led to three goals from Monaco, with Lamine Camara, Breel Embolo, and Christian Mawissa finding the net. Head coach Hansi Flick's substitutions were met with criticism, particularly for Ilkay Gundogan's performance, which some fans felt slowed the team's momentum. This defeat raises concerns for Barcelona as they prepare for their La Liga opener against Valencia, with questions about their defensive solidity and overall team cohesion. The loss adds pressure as they face a competitive season ahead, especially with rivals like Real Madrid strengthening their squad.
