On 3 May 2014, Callejón set up Dries Mertens for the third goal in a 3–1 win against ACF Fiorentina in the final of the Coppa Italia. He scored once in the final game of the season, a 5–1 home rout of Hellas Verona F.C. on 18 May; his strike after five minutes was Napoli's 100th goal in all competitions that season, and his 20th overall.
