The Defining Moment
Roma’s defensive unit entered 2026/27 as the foundation upon which Gian Piero Gasperini would build his first season in the capital. The previous campaign had ended with just 31 goals conceded — the second-best record in Serie A — and the summer recruitment was designed not to overhaul that base, but to deepen it. The arrivals of Leonardo Balerdi from Tottenham, Konstantinos Koulierakis from Wolfsburg, and Nahuel Molina from Atlético Madrid reflected a clear strategy: Gasperini wanted options, not revolution.
The defining characteristic of Roma’s defensive season has been the sheer depth at Gasperini’s disposal. With Evan Ndicka, Gianluca Mancini, Mario Hermoso, Balerdi, Koulierakis, and Ghilardi all available, the Giallorossi possess “six almost interchangeable centre-backs” — a luxury few Serie A clubs can match. Gasperini has rotated freely, managing the demands of Serie A and Champions League football without a significant drop in quality.
This is the story of Roma’s 2026/27 defenders: a unit built on continuity, deepened by smart recruitment, and tasked with sustaining the standards that have made the Giallorossi one of Italy’s most resilient sides.
Tactical Context
Gasperini’s arrival brought a structural shift to Roma’s defensive setup. The former Atalanta architect favours a back three, with wide centre-backs expected to step into midfield and full-backs or wing-backs providing width. The system demands defenders who are comfortable in possession, capable of progressing the ball under pressure, and intelligent enough to cover the large spaces that Gasperini’s high line leaves behind.
The early-season numbers reflect a team still adjusting but already formidable. Roma conceded just ten goals in their opening ten Serie A matches, a rate of 1.00 per game, while keeping clean sheets in four of those fixtures. Their away record was particularly impressive: just three goals conceded in five matches on the road, with a defensive rate of 0.75 per game. The unit ranked among Europe’s best over the past two seasons, tied with Arsenal for the most clean sheets across Europe’s top five leagues.
The tactical question for Gasperini is not quality but cohesion. With six centre-backs competing for three positions, the challenge is maintaining the understanding and communication that a back line requires. Ndicka, Mancini, and Hermoso represent the established trio, but Balerdi’s emergence and Koulierakis’s potential offer genuine alternatives. Gasperini’s rotation policy has kept everyone engaged, but the margins in Serie A are thin, and a single lapse in concentration can prove costly.
The Defenders
Evan Ndicka
Ndicka is the defensive cornerstone and the player upon whom Gasperini’s back three depends. The Ivorian international has established himself as one of Serie A’s most complete centre-backs, combining physical presence with recovery pace and composure in possession. His ability to defend large spaces is essential in Gasperini’s high-line system, and his left-footed profile offers balance in the defensive trio.
At 27, Ndicka is in his prime. His partnership with Mancini and Hermoso has provided the stability that Roma’s defensive record reflects, and his availability has been one of the few constants in a season of rotation. The concern is not quality but workload: Ndicka has been a fixture in the starting line-up, and Gasperini must manage his minutes carefully as the season progresses.
Gianluca Mancini
Mancini is the veteran presence and the emotional leader of the defensive unit. The Italian international’s aggression and aerial dominance have been central to Roma’s resilience, and his experience of Serie A’s demands provides a reference point for the younger defenders around him. His leadership was recognised with the captain’s armband in several matches this season.
At 30, Mancini remains a reliable performer, though his occasional rashness in the tackle can expose the team. In Gasperini’s system, his role is to defend the central corridor and provide the physical edge that the back three requires. His partnership with Ndicka and Hermoso has been the foundation of Roma’s defensive solidity.
Mario Hermoso
Hermoso has been one of the season’s quiet revelations. The Spanish centre-back, whose Roma career appeared to be drifting after a difficult loan spell at Bayer Leverkusen, has re-established himself as a key figure under Gasperini. His left-footed profile and ability to step into midfield have made him an ideal fit for the system, and his leadership qualities have been recognised with a contract extension reportedly in progress.
At 31, Hermoso has accumulated 1,049 minutes across Serie A and the Champions League — second only to Wesley Teixeira in the squad — and has contributed three goals, including a crucial opener against Sassuolo. His form has been so impressive that Roma have moved to extend his contract by one to two years, with an option for a further season.
Leonardo Balerdi
Balerdi is the summer addition who has exceeded expectations. The Argentine centre-back arrived on loan from Tottenham with a purchase option, viewed as a depth option rather than an immediate starter. His impact has been immediate and significant: a double against Napoli, charisma, and elegance in possession have made him a fan favourite and a genuine challenger for a starting role.
At 27, Balerdi offers a combination of physicality and technical quality that suits Gasperini’s system. His ability to play out from the back and his aerial presence have given Roma a different dimension in defence. The loan arrangement includes a purchase option, and his performances are making a strong case for activation.
Konstantinos Koulierakis
Koulierakis is the long-term project. The Greek centre-back arrived from Wolfsburg for approximately €15 million, identified as a player with the potential to develop into a fixture of Roma’s defence for years to come. At 22, he has been used sparingly — 225 minutes across eight appearances — but Gasperini’s decision to start him against Genoa and Cagliari demonstrated trust in his ability.
His left-footed profile and physical development suggest a player who can mature into a complete centre-back. For now, his role is rotational, learning alongside Ndicka, Mancini, and Hermoso while adapting to the demands of Gasperini’s system.
Nahuel Molina
Molina is the experienced full-back signed permanently from Atlético Madrid to provide width and quality on the right flank. The Argentine international, a World Cup winner in 2022, brings 249 appearances in European competition and a profile ideally suited to Gasperini’s demands: aggressive, attacking, and comfortable in advanced positions.
His adaptation to Serie A has been smooth, and his understanding with the right-sided centre-back has developed steadily. At 28, Molina is in his prime, and his contribution to both phases of the game has been valuable in a season that includes Champions League football.

Tactical Identity & Squad Balance
Roma’s defensive unit is a study in depth and continuity. Gasperini inherited a back line that had already established itself among Serie A’s best, and the summer recruitment added quality without disrupting the balance. The result is a group of six centre-backs who can rotate without a significant drop in standards, supported by full-backs who provide width and attacking thrust.
The early-season numbers validate the approach. Roma’s defensive record is among the best in the division, and their away form — just three goals conceded in five matches — reflects a unit that travels well and absorbs pressure. The clean sheets against Fiorentina, Lecce, and Torino demonstrated the capability that Gasperini’s system demands.
The concern is not the starting XI but the workload. With Champions League football adding to the fixture list, Gasperini must manage his defensive resources carefully. The depth is there, but the cohesion that comes from a settled back line is difficult to maintain when rotation is constant. The January window is unlikely to bring defensive reinforcements — Roma’s priorities lie further forward — but the current group possesses the quality and quantity to sustain a challenge on multiple fronts.
The Verdict from the Camp
Rivista La Roma on Gasperini’s defensive depth:
“The strength of the Giallorossi defence also lies in the quality and depth of its interpreters. Ndicka, Mancini, Balerdi and Hermoso represent the first choices, while Ghilardi and Koulierakis complete a department that is hard to compare with others in Serie A.”
IlRomanista on Balerdi’s impact:
“The other surprise is Leonardo Balerdi, a last-minute signing capable of climbing the pecking order and carving out an important space: not only the double against Napoli, the Argentine shows charisma and elegance in every play.”
Torino Sport on Hermoso’s renewal:
“Roma will renew Elio Hermoso for one or two seasons. The Spanish defender, after completely turning his situation around, has become an indispensable pillar in Gasperini’s system.”
Where Next?
Roma’s defensive priority for 2026/27 is preservation and rotation. The unit possesses the quality to sustain a Serie A title challenge and compete in the Champions League, but the demands of the fixture list require careful management. Ndicka, Mancini, and Hermoso remain the established trio, but Balerdi’s form and Koulierakis’s potential offer Gasperini genuine alternatives.
The longer-term picture is settled. Ndicka is contracted until 2030, Hermoso’s renewal is in progress, and Balerdi’s loan includes a purchase option that his performances are making increasingly likely to be activated. Molina provides experience on the right, and the academy pathway remains open for future graduates.
For now, the focus is on maintaining the standards that have defined Roma’s season. The defensive record is among the best in Italy, and the depth at Gasperini’s disposal is a luxury few clubs can match. If the unit can stay fit and cohesive, Roma’s foundation is secure. If rotation disrupts the understanding that has developed, the margins in Serie A are thin enough to punish any lapse.
