Luca Marrone is an Italian footballer who plays as a central midfielder for Serie A club Juventus.

Marrone, a childhood Juventus fan, joined the Juventus youth set-up as a six-year-old and made his way up the youth ranks all the way to the Primavera youth squad for the 2007–08 season. After impressing in the Primavera side, new Juventus head coach and former youth director at the club Ciro Ferrara called Marrone to join the first team squad for the 2009–10 pre-season. After taking part in a number of friendly games and tournaments, including the Peace Cup and the TIM Trophy, Marrone was called up to the Juventus bench for the season opener against Chievo Verona, and went on to make his Serie A debut coming on as a 70th minute substitute for Tiago.He also received a yellow card later in that match. In September, he made his second appearance against Livorno as a late substitute for Mauro Camoranesi and was also named on the bench for a number of important Serie A and European matches.

In February 2010, he captained the Primavera team to a successful defence of the Viareggio Tournament title. He was also called-up for the summer training camp with the first team.
