Arsenal will be without Granit Xhaka, for their Europa League quarterfinal second-leg clash with CSKA Moscow in Russia on Thursday.
The Switzerland midfielder has been left at home, as he is down with flu.
Xhaka had started the first leg last week, which the Gunners won 4-1 at the Emirates, as well as both games of the round-of-16 tie against AC Milan, in which he scored in the second leg.
But he will not be available in Moscow and Arsene Wenger could turn to Mohamed Elneny in midfield in Xhaka’s place.
Henrikh Mkhitaryan has already been ruled out after suffering a knee injury in the first leg.
