However, this competition now represents Arsenal's only chance to win a trophy and secure Champions League football for next season, which could tempt Wenger to switch to Cech, his normal No. 1.

Arsenal have won their last four matches in all competitions, and they dismissed a decent Milan team 5-1 on aggregate in the previous round.

The game will be played against the backdrop of diplomatic tensions between Russian Federation and Britain in the wake of the poisoning of a former spy on United Kingdom soil.
