Arsenal managed to scrape a slender 1-0 victory against Red Star Belgrade in the Serbian capital on Thursday evening, sending them five points clear of their opponents at the top of Group H.
Red Star surprisingly have something many Gooners will be envious of - a European Cup - and the last time the two teams met was back in 1978 in what was the UEFA Cup, with the Serbian side coming out on top.
Arsene Wenger opted for an unconventional back three of Rob Holding, Mohamed Elneny and forgotten man Mathieu Debuchy behind a young midfield including Reiss Nelson, Ainsley Maitland-Niles and Joe Willock.
