Pierre-Emerick Aubameyang may be cup-tied for Arsenal in European competition but the Gabon striker spurred his team-mates on alongside his wife and kids on Thursday.
Arsene Wenger's side welcomed Swedish minnows Ostersund to the Emirates after a comfortable 3-0 win away in the first leg.
But it was a far more testing affair in north London as the visitors scored twice to set hearts racing among Aubameyang and the rest of the home supporters, only for defender Sead Kolasinac to ensure the Premier League side progressed to the last-16.
