Granada coach Tony Adams' matchday suit had Real Madrid midfielder Isco in stitches on Saturday.
Real were comfortable winners against relegated Granada, hitting four goals in the second-half.
Movistar+ cameras caught Isco mocking the Arsenal legend during the match.
When Adams took off his jacket to reveal he was wearing a vest underneath, Isco joked with teammates in the Real dugout: "Waiter! A Coke!"
