Bayern Munich staged a remarkable comeback to defeat Arsenal 5-2 in their Champions League Group C opener, with Pernille Harder delivering a stunning performance by scoring a hat-trick in just 13 minutes. Arsenal initially took the lead in the first half thanks to Mariona Caldentey, but the match quickly turned in favor of the energized Bayern side. After goals from Sydney Lohmann for Bayern and Laia Codina for Arsenal, Harder’s explosive scoring spree sealed the game for the German team. This early defeat raises concerns for Arsenal, as they face a crucial week ahead, including a match against Chelsea in the Women’s Super League on Saturday. The manner in which Arsenal conceded the last three goals will be particularly frustrating for manager Jonas Eidevall, as the pressure on the team continues to grow. The significance of this loss could have lasting implications for Arsenal's season.
