Second half goals from Lyon substitute Mousa Dembele ensured Lyon lifted the Emirates Cup at Arsenal's expense, after Pierre-Emerick Aubameyang had given the Gunners the lead.
It was all Arsenal in the first half, and after Henrikh Mkhitaryan forced a stunning save from Anthony Lopes with a stinging volley from 15 yards, the Armenian turned creator, as his fizzing cross was converted by Aubameyang.
The 30-year-old was leading the line well, drafted in from the left wing after Alexandre Lacazette was taken off as a precaution in the opening ten minutes, and his second goal of pre-season was everything his side's performance merited in the first 45.
