Emmanuello was a youth product of Juventus. He was an overage player for the under-19 youth team in the first half of 2013–14 season.
Atalanta
On 31 January 2014 Juventus swapped half of the registration rights of Emmanuello (for €1.5 million price tag) with the 50% rights of Davide Cais (for €1.54 million),[4][5] The deals made Juventus register a profit of about €1.5 million in the 2013–14 season (a potential profit of €1.5 million would be registered in the future season) and about €3.1 million in Atlanta's 2014 financial year (a potential loss of €1.54 million would be registered in the future season), despite the increase was in terms of intangible assets. Emmanuello immediately left for Pro Vercelli.
On 24 June 2015 Atlanta bought Emmanuello outright for another €800,000, with Cais moved to Juventus also for €800,000.[6][7]
Pro Vercelli (loan)
On 31 January 2014 Emmanuello was signed by Piedmontese club Pro Vercelli in a temporary deal, re-joining Juventus team-mate Giuseppe Ruggiero.
Pro Vercelli won promotion back to Serie B in 2014. In June 2014 the loan and co-ownership were renewed.[8][9] Emmanuello remained in Pro Vercelli for 2014–15 season. In June 2015 Emmanuello joined Atalanta outright. He remained in Vercelli again for 2015–16 season,[10] as no.14 of the first team.[11]

He received his first competitive call-up for the team in 2018–19 Coppa Italia Serie C [it] on 20 August.[14] Emmanuello made his league debut against Alessandria on 16 September.[15] As Juventus B also used Stadio Giuseppe Moccagatta as their home stadium,[16] the match was also a local derby.
