Arsenal stun Lyon 3-0
At the Al Maktoum Stadium, all three goals were scored in the opening period.
In the 19th minute, Gabriel headed in a corner to open the scoring.
Eddie Nketiah and Fabio Vieira added quickfire efforts in the 33rd and 39th minutes.
Lyon's lineup under former France coach Laurent Blanc featured ex-Arsenal striker Alexandre Lacazette.
But the 31-year-old failed to find the net against his former employers before being taken off in the second half.
