Mertens subs in then scores for Napoli is a phrase that became almost synonymous with the Belgian forward across nearly a decade at the Stadio Diego Armando Maradona, and the sheer frequency with which it occurred stands as a testament to one of Serie A’s most prolific impact players.
Dries Mertens made the art of the super-substitute goal a recurring feature of Napoli’s attacking play long before he transitioned into the lead striker role that would make him the club’s all-time record goalscorer.
The Origins: Mertens Subs In Then Scores in His Earliest Napoli Years
When Mertens joined Napoli from PSV Eindhoven in 2013 for a reported fee of €9.6 million, he arrived as a wide forward accustomed to providing energy and directness from the flanks rather than carrying primary goalscoring responsibility.
His first significant Serie A impact in a substitute role came on 30 October 2013, when he came off the bench and scored the winner in a 2-1 victory away at Fiorentina — a moment that immediately established his capacity to influence matches from second-half introductions.
Over the following two and a half seasons, Mertens compiled his most prolific work as an impact substitute, regularly emerging from the bench in the second half to create or score decisive goals in tight matches, contributing at least 10 goals across all competitions in each of those campaigns.
One of the most dramatic examples came in the Coppa Italia final of May 2014, when he entered the field as a replacement for Marek Hamsik in the 64th minute and scored in stoppage time to seal a 3-1 victory over Fiorentina — his ability to stay sharp during extended periods on the bench and deliver in high-pressure moments was already clearly evident.
The Transformation and the Record That Endures
The pivotal shift in Mertens’ role came in the 2016-17 Serie A season, when the departure of Gonzalo Higuain to Juventus and a serious injury to replacement striker Arkadiusz Milik forced then-manager Maurizio Sarri to repurpose Mertens as a central striker.
The experiment produced one of the most celebrated individual seasons in Napoli’s modern history, with Mertens scoring 28 league goals in 35 Serie A appearances and earning a place in the league’s team of the year.
Even within that campaign, however, his habit of subbing on and scoring persisted as one of his defining characteristics, particularly in European fixtures and domestic cup ties where his starting role was not always guaranteed.
On 11 December 2016, he scored a hat-trick in a 5-0 league victory over Cagliari, and followed it with a four-goal performance in a 5-3 win over Torino the following match — the most explosive stretch of form in his Napoli career.
In February 2020, Mertens made club history when he surpassed the great Marek Hamsik to become Napoli’s all-time record goalscorer, eventually ending his time at the club with 148 goals across all competitions — a figure that includes a remarkable number scored after entering the field as a substitute.
He departed Napoli in 2022 to join Galatasaray, where he continued contributing goals and assists until announcing his retirement from professional football in June 2025, having helped the Istanbul club secure a fifth consecutive Süper Lig title.
In a career spanning more than a decade at the highest level of European club football, few moments captured the essence of Mertens more precisely than those recurring second-half entries at the San Paolo — a player who could change a game not with a full ninety minutes, but with fifteen purposeful ones.
