George Ilenikhena made a sensational debut for AS Monaco in the UEFA Champions League, scoring the decisive goal in a 2-1 victory over Barcelona. The match saw Monaco take an early lead through Maghnes Akliouche, followed by a quick equalizer from Barcelona's Lamine Yamal. Barcelona was reduced to 10 men after Eric Garcia received a red card just 10 minutes into the match for a foul on Takumi Minamino. Ilenikhena's goal came in the 71st minute, marking his first for Monaco since joining from Royal Antwerp for €18.75 million. The defeat adds to Barcelona's recent struggles in European competitions, as they continue to face challenges away from home. Ilenikhena's goal also made him the youngest scorer for Monaco in the Champions League, surpassing a record previously held by Kylian Mbappe.
