Dani Olmo made a sensational debut for Barcelona, scoring the winning goal in a 2-1 victory against Rayo Vallecano, after initially facing registration issues that delayed his participation. Barcelona, under coach Hansi Flick, has started the La Liga season with three consecutive wins despite injuries to key players like Frenkie de Jong and Ronald Araujo. Olmo's impactful performance, described by Flick as exceptional, showcased his ability to enhance the team's control and creativity on the ball. The victory not only maintains Barcelona's perfect record but also increases pressure on rivals like Real Madrid. This match marked a significant comeback for Olmo, who returned to Barcelona after previously leaving their youth academy for Dinamo Zagreb ten years ago. The circumstances surrounding his registration were complicated, but an injury to Andreas Christensen allowed for his inclusion in the squad, leading to a memorable debut.
