Barcelona missed their chance to reach the knockout round of the UEFA Champions League 2023-24 with games to spare after a shock 1-0 loss to Shakhtar Donetsk in Hamburg on Tuesday. It was Shakhtar's first win as a host in the group stage of the competition since they started playing away from Ukraine because of the war with Russia. A draw would have been enough to secure Barcelona a spot in the round of 16 for the first time after two straight eliminations in the group stage of Europe's top club competition. The result also ended Barcelona's perfect Champions League record this season and moved Shakhtar into position to also advance from Group H. Meanwhile, Paris Saint-Germain too had to endure a 1-2 away defeat at the hands of AC Milan. Rafael Leao and Olivier Giroud scored early in each half to help Milan recover from conceding a ninth-minute opener to former Inter Milan defender Milan Skriniar and give their team its first group win.
