Arsenal star Granit Xhaka is out of Arsenal's Europa League quarter-final clash against CSKA Moscow after developing a flu.
The Swedish international did not travel to Russia with the rest of the Arsenal squad yesterday.
Xhaka was part of the team that beat CSKA 4-1 at home last week.
Former Manchester United star Henrikh Mkhitaryan has also been ruled out with a knee injury.
Arsenal are three goals ahead as they take on CSK Moscow tonight.
