Arsenal, who traditionally wear their red and white jersey, will be seen in a unique kit combination for their Champions League opener against Athletic Club. While the specific details of the kit have not been revealed yet, it is expected to deviate from their usual home or away colors.

The change in kit combination for Arsenal's Champions League opener is likely due to a color clash with the home kit of Athletic Club. This is a common practice in football where teams have to adjust their kit to ensure clarity and avoid any confusion on the pitch.
