At age eight, Marrone joined the Juventus youth system and made his way through the ranks of the Juventus F.C. Youth Sector all the way through to the Primavera (under-20) youth squad for the 2007–08 season. After impressing in the Primavera side for a couple of seasons, then–Juventus head coach and former youth director at the club Ciro Ferrara called Marrone to join the first team squad for the 2009-–10 Serie A pre-season. After taking part in a number of friendly matches and pre-season tournaments, including the Peace Cup and the TIM Trophy, Marrone was called up to the Juventus bench for the season opener against Chievo Verona. He went on to make his Serie A debut 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 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 once again called up for the summer training camp with the first team prior to the 2010–11 Serie A season under new head coach Luigi Delneri.
On 1 July 2010, Marrone was sent to Siena with former Primavera teammate Ciro Immobile on a season-long loan deal in order to gain regular first-team playing time. He had a relatively successful spell with the Serie B side under former Juventus player Antonio Conte and helped the side reach second-place and gain automatic promotion back to Serie A.
Marrone returned to Juventus on 30 June 2011 upon the expiration of the loan deal. He was to be loaned out again until Conte, who had been recently appointed new Juventus manager, blocked the move and included the youngster in his plans for the upcoming season. He made his first start for the club in the Coppa Italia fixture against Bologna and first appearance of the season away at Lecce in January. His first assist came in an away victory against Atalanta. He started his first Serie A match and scored his first top-flight goal in the return leg against the club from Bergamo on the last matchday of the season, as Juventus won the Scudetto undefeated.
Marrone started in the opening match of the 2012–13 season against Parma in a 2–0 win, replacing the injured Giorgio Chiellini in an unfamiliar position as centre back but managed to help keep a clean sheet. Throughout the remainder of the 2012–13 Serie A campaign, he was regularly utilized in central defense after that match. For the second season running, Marrone and Juventus finished the campaign as champions of Italy.
Initially part of the first-team plans for Juventus prior to the start of the 2013–14 Serie A season, Marrone was sold to newly-promoted Serie A side, Sassuolo on 2 September 2013 on a co-ownership deal. The deal served as an exchange for 50% of the contract of Sassuolo's Domenico Berardi who joined Juventus on a co-ownership deal but remained at Sassuolo on loan for the 2013–14 campaign. Marrone's season with the neroverdi began well, but was ultimately hampered by injuries that limited the midfielder to just 15 league appearances. On 20 June 2014, the co-ownership deal was renewed between Sassuolo and Juventus with Sassuolo retaining the playing rights for the player.
Return to Juventus
On 3 July 2014, however, Marrone returned to Juventus once more after Juventus bought out the remaining 50% of his contract from Sassuolo in a deal worth €5 million euros that will be paid over the course of the next three seasons. He also signed a five-year contract that binds him to Juventus on 30 June 2019
Marrone made his debut with the Italy U-21 squad on 13 October 2009, under coach Pierluigi Casiraghi, in a qualifier match against Bosnia-Herzegovina. In March 2010, he scored his first goal for the Azzurrini, a 20-yard volley, in a 2–0 victory over Hungary to put them second in their qualifying group. Under former Primavera coach Ciro Ferrara, he continued to be a regular.
