Arsenal's captain Martin Ødegaard is expected to be sidelined for six weeks due to a knee injury he suffered before the international break. This is a significant blow for the team as they rely on his leadership and skills on the pitch. His absence could impact their performance in upcoming matches, but players like Eberechi Eze and Ethan Nwaneri are set to step in during his recovery. Fans are hopeful that Ødegaard will return in time for the crucial north London derby in November.
