Arsenal were knocked out of the UEFA Youth League earlier this week as they were beaten by Barcelona in Spain.
The Catalan club took the lead through Munir El Haddadi after half an hour but Serge Gnabry soon leveled up the scores.
Adama Traore put Barcelona back in front but refusing to give in, Chuba Akpom equalised for the Gunners.
The dismissal of Dejan Iliev didn’t help Arsenal’s cause and they were undone by two late goals. Wilfrid Kaptoum put them 3-2 ahead before Traore grabbed his second and secured the victory.
