On 29 November 2008, Enzo Maresca was Sevilla's defensive midfielder when Pep Guardiola's high-flying Barcelona were the visitors.
It would turn out to be a key moment in his career. A lightbulb moment of clarity, when thoughts the 28-year-old Maresca had on how the game should be played were turned on their head.
It would be more than eight years before he, as a young coach, could begin to try to put into practice what he had witnessed that night when Barca strolled to a 3-0 victory as Sevilla spent most of the game trying to figure out how to get the ball.
