Mikel Arteta expresses concern over Odegaard's significant injury, says Arsenal boss

The midfielder encountered a setback during his time with Norway last week.

Ahead of Thursday's Champions League tie with Atalanta, Artera said: "The scan showed some damage around the ligaments in the ankle so we are going to miss him.

"It's something quite significant so we are going to lose him for a while. Hopefully not months.

"He's our captain," added Arteta. "He's been one of the biggest and best players in our team.

"Our identity is very linked to how he plays and behaves. It's a big test for the team to see how able we are to show a different face."
