Odegaard has missed Arsenal's last six games with the injury he suffered playing for Norway last month, an absence that has forced Arteta to change his plans. Arteta said that the midfielder was "working so hard" to return, but the Gunners boss could not pinpoint when he would be back in action.
Leandro Trossard has come in for the top-flight games missed by Odegaard, as well as the Champions League win over Paris Saint-Germain this week. In a tweak to Arsenal's usual 4-2-3-1 formation, Kai Havertz has played alongside the Belgian in a two-man strike partnership.
Arsenal's ability to adapt in Odegaard's absence has helped them remain one of unbeaten sides in the Premier League. "We had to be different," said Arteta.
