Lyon clinched the 2019 Emirates Cup with a 2-1 victory over Arsenal thanks to two goals from Moussa Dembele.
Pierre-Emerick Aubameyang gave the Gunners the lead on 35 minutes when he bundled home Henrikh Mkhitaryan’s cross after some good pressing from Unai Emery’s men.
However, Lyon were level on 66 minutes when Dembele headed home Memphis Depay’s cross.
Arsenal thought they had re-taken the lead when summer signing Gabriel Martinelli squeezed the ball home, but the Brazilian saw his effort ruled out for offside. Then Lyon broke down the other end and Dembele kept his cool to slot past Bernd Leno.
The defeat was Arsenal’s first in preseason, having so far claimed victories over Colorado Rapids, Bayern Munich, Fiorentina and a draw against Real Madrid before succumbing on penalties.
They face Angers on Wednesday before playing Barcelona on Sunday in their final friendly before they start their Premier League campaign at Newcastle.
