I'm not sure if I'm just not used to hearing it, but with the female voice I really can't hear it saying "Jouons". The "ons" seems absent, though I hear it in the turtle speed. Maybe I'm just not used to hearing the "ons" before the "au"? I reported it anyway.
It is not wrong and it is accepted. FR "football" = "football" everywhere in the world. Although in the U.S., the game referred to in the French sentence is what is called "soccer" over here. In the global community, FR "football" = football (but not "American football").
