Mesut Özil missed Arsenal's first home Premier League game of the season against Burnley because of illness.
The German midfielder missed the Gunners' opening day victory against Newcastle due to safety concerns - he and teammate Sead Kolasinac were victims of an attempted carjacking by an armed gang - but it was expected that Özil would return to the squad for Saturday's game at the Emirates.
But in the lead up to the game, manager Unai Emery hinted that Özil may not feature at the weekend because he had missed training through illness, even though he and Kolasinac were '100%' ready to play after their traumatic ordeal.
