Allegri and Sarri first played against each other in Serie C in 2008. Sarri went with five at the back, it didn't work. Story tells that this was the day that resulted in the birth of Sarriball. Sarri couldn't cope with being so outplayed by this 40 year old carefree smily Tuscan. As a Napolitano it was too much for his pride so he simply copied Max's formation and tactics. So in truth Sarriball was conceived by Max. True story.
