Siena Born in
Bucharest, Romania Marcone started his professional career at Italian club
Siena. He joined the Tuscan team from Esperia in temporary deal on 30 August 2007. The deal later turned to definitive deal. He was the member of the under-20 team in 2010–11 and 2011–12 season, and previously U17 youth team in 2008–09 and 2009–10 season. Marcone also occasionally worked with first team as fourth keeper in
2011–12 Serie A. He wore no.93 shirt, his year of birth.
Vicenza In June 2012, the club decided to capitalise his potential market value. Despite no real buyer from Serie A and B clubs nor he could enter the first team immediately, the club used player exchange to give an accounting value to the player, in order to pass the financial benchmark of
FIGC. He was swapped with
Giulio Cavallari of
Vicenza Calcio in
co-ownership deal, while Marcone's team-mate
Alessandro Iacobucci (keeper), who spent 2011–12 season in
South Tyrol, were swapped to Parma along with
Pacini and
Rossi. Moreover the deal was completed on 29 June 2012, the second last day of 2011–12 financial year, which ended on 30 June. However, his new "market" value to his new club, would be a cost in term of
amortization as a kind of intangible asset. Half of Marcone was "valued" €750,000 and Cavallari €768,000, made only €18,000 cash involved. Marcone signed a 3-year contract. In July 2012, Marcone left for
South Tyrol (, ) to replace Iacobucci, who left for
Spezia, a Serie B club. On the next day South Tyrol also signed
Matteo Grandi from
Cesena. Marcone successfully became the first choice and Grandi as deputy.
Trapani In June 2013, Siena sold Marcone outright to Vicenza as well as Cavallari to Siena from Vicenza outright. However, both clubs once failed to register in Serie B (Siena) and Lega Pro Prima Divisione (Vicenza) On 10 July Vicenza finally acquired all the required document for the new season. However due to the present of former Italian under-21 internationals
Carlo Pinsoglio who was the first choice of last season, Marcone was immediately left for
Trapani Calcio in temporary deal with option to purchase. On 10 July 2014
Trapani acquired Marcone outright for €200,000 and
Daniele Martinelli outright for an undisclosed fee. On 21 July 2015 Marcone was re-signed by
Vicenza Calcio in a temporary deal, with an option to buy. He wore no.1 shirt. On 26 January 2016 Marcone was signed by Serie A club
Verona. He wore no.88 shirt. On 12 July 2016 was re-signed by South Tyrol. On 31 August 2017 he left for
Pro Vercelli.
Rieti On 31 January 2019, he joined
Rieti.
Ternana On 13 September 2019 he joined
Ternana on a one-year contract.
Potenza On 18 November 2020, Marcone signed for
Serie C club
Potenza as a free transfer, re-joining his former Rieti boss
Ezio Capuano, and making his debut on the same day in an away game against
Palermo.
Avellino On 7 July 2022, he joined
Avellino on a two-year deal.
