In the 2014 Supercoppa Italiana in Doha on 22 December 2014, Jorginho entered the game against Juventus in the second half of extra time in place of Jonathan de Guzmán. He took Napoli's first spot-kick in the penalty shootout, and although Gianluigi Buffon saved it, Napoli were eventually victorious. While initially struggling to get into manager Rafael Benítez's lineup, Jorginho's fortunes changed with the appointment of Maurizio Sarri who was key to his development, deploying him in a deep-lying midfield role from which he could dictate play with his passing. In 2017–18, Jorginho had a breakthrough season with Napoli and was integral to their Serie A title challenge.
