Arsenal captain Martin Odegaard is set for an extended absence after sustaining 'significant' ankle ligament damage during international duty with Norway. Manager Mikel Arteta confirmed that Odegaard will miss key fixtures, including the Champions League opener against Atalanta and upcoming Premier League matches against Manchester City and Tottenham Hotspur. The injury has raised concerns among fans and puts pressure on the team to adapt without their influential playmaker. Initial estimates suggested he could be sidelined for at least three to four weeks, but the extent of the damage may prolong his recovery. With Odegaard being the lone attacking midfielder, Arsenal faces challenges in maintaining their style of play during his absence, particularly with recent departures of other midfielders. The club's reliance on 17-year-old Ethan Nwaneri may become critical as they navigate this difficult phase.
