Answer
Antonio Conte was never the manager of Vincenzo Iaquinta at Juventus. Iaquinta played for Juventus from 2007 to 2013 under managers Didier Deschamps, Ciro Ferrara, Alberto Zaccheroni, Luigi Delneri, Antonio Conte, and Massimiliano Allegri. Conte managed Juventus from 2011 to 2014, after Iaquinta had left the club.
