Emiliano (formerly Damian) Martinez will make his Champions League debut for Arsenal on Wednesday night.
With David Ospina injured, and Wojciech Szczesny suspended due to his red card against Galatasaray, Arsene Wenger will hand a European debut to the 22 year old Argentine.
Martinez has previously made just two appearances for the club, both in the Capital One Cup. He endured a difficult first half in that extraordinary 7-5 win over Reading, but had an easier night in a 6-1 triumph over Coventry.
Now the third choice pick, he’ll have a chance to impress in the Champions League, although further enforced changes to the Arsenal backline might be seen as a worry given the inability to select a consistent group so far this season.
19 year old Deyan Iliev is likely to travel to Belgium as the substitute keeper.
