Fans were left bemused after Arsenal and Lyon held a penalty shootout despite the Gunners running out 3-0 winners.
First-half goals from Gabriel Magalhaes, Eddie Nketiah and Fabio Vieira secured victory for Mikel Arteta's side on Thursday.
Despite the convincing win, the two sides still held a penalty shootout in the first of their Dubai Super Cup fixtures.
This left fans confused as one tweeted: 'Someone pls enlighten me. Why do they have to have to play penalty shootouts when Arsenal have won the game 3-0 on normal time. I'm confused.'
A second said: 'Despite winning 3-0, Arsenal's game against Lyon has gone to a penalty shootout due to the tournament's bizarre rules.'
And a third added: 'Wait how did Arsenal win 3-0 then go to penalties? I'm so baffed someone explain.'
Arsenal secured a bonus point by winning a penalty shootout 2-1, with goalkeeper Karl Hein making four saves in a low-quality contest.
The worst penalty was saved until last as Rayan Cherki's Panenka was caught by Hein, with the Estonian making his fourth save.
And fans were not impressed.
One fan tweeted: 'Probably the worse penalty shoot out ever seen.'
A second said: 'I've just seen some of the worst penalties from both teams, worse than Spain against Morocco.'
A third added: 'Tell me the penalty shootout was a joke.'
The result gives Arsenal four points at the start of the friendly competition, which also features Liverpool and AC Milan.
Arsenal will face the Italian champions on Tuesday before flying back to London to continue their preparations for the resumption of the Premier League season.
