Arsenal's Martin Odegaard and Harvey Elliott set for spells on sidelines after international injuries

Arsenal captain Martin Odegaard is set to be out for around three weeks with an ankle problem he sustained on international duty, according to Norway's team doctor.

The Gunners midfielder was left clutching his left ankle on Monday night after an innocuous-looking tangle with Austria’s Christoph Baumgartner on the hour mark of his side’s 2-1 Nations League win in Oslo and was helped off the pitch in tears by team-mate Erling Haaland.
