Alexia Russo admits that Arsenal is going through a challenging period after starting their Champions League title defense with a 2-1 loss to Lyon. All goals were scored within the first 23 minutes, with Russo opening the scoring from a Beth Mead assist, but Lyon quickly responded with two goals from Melchie Dumornay. Defensive errors, including careless play from Daphne van Domselaar and Mariona Caldentey, allowed Lyon to overturn the result. Arsenal's coach, Rene Slegers, acknowledged the team's failure to impose their game and highlighted the need for better physical and tactical preparation for upcoming matches. Despite the tough start, Russo remains optimistic about the team's ability to overcome challenges and improve their performance.
