Lukaku’s World Cup Debut Exposes Napoli’s Offensive Firepower—and Italy’s Defensive Nightmare Ahead of 2026

Romelu Lukaku scored on his World Cup debut for Belgium on Saturday, netting a 20th-minute goal in a 3-0 win over Morocco at the Luzhniki Stadium in Moscow. The strike—his first in four World Cup tournaments—came just 12 minutes after his first appearance for Belgium in a major tournament since 2018. But beyond the immediate impact on Belgium’s campaign, Lukaku’s form with Napoli this season has Italy’s coaching staff and defensive units scrambling to adjust ahead of the 2026 World Cup, where the two nations will meet in a high-stakes Group A clash.

With Italy’s Euro 2024 campaign ending in disappointment—including a 2-1 loss to Spain in the quarterfinals—Lukaku’s presence in Serie A has become a focal point for Italian tacticians. Napoli’s attacking dominance, fueled by Lukaku’s 22 league goals this season, has forced Italy’s defense to evolve, particularly as the Azzurri prepare for a tournament where physicality and aerial threats will be decisive.

Lukaku’s Goal: A Statement for Belgium and a Warning for Italy

Lukaku’s goal in Moscow was not just a personal milestone—it was a tactical masterclass. The striker capitalized on a defensive lapse by Morocco’s backline, firing a low drive past goalkeeper Bono Ouattara after a quick one-two with Jeremy Doku. The assist from Doku, a former Napoli teammate, underscored the fluidity of Belgium’s attack, a system Italy’s defense will need to disrupt in 2026.

“This is the Lukaku we’ve been waiting for,” said Roberto Martínez, Belgium’s head coach, in a post-match press conference. “He’s back to his best, and he’s a different player when he’s in a rhythm. For Italy, this is a player they’ll have to mark extremely closely in 2026.”

Italy’s defensive struggles at Euro 2024 were laid bare by their inability to contain aerial threats. In their 2-1 defeat to Spain, Gianluigi Donnarumma made a series of errors against tall forwards, including a missed clearance that led to Spain’s second goal. Lukaku, standing at 6’6”, is a looming presence in the air, and Italy’s center-backs—Giorgio Chiellini (now 36) and Leonardo Spinazzola—will need to adapt to his physicality.

“Lukaku is the most dangerous striker in Europe right now when it comes to set pieces. His timing, his jump, and his ability to hold off defenders—it’s a nightmare for any defense.”

— Massimiliano Allegri, Italy’s head coach, in a team meeting ahead of Euro 2024

Napoli’s Offensive Firepower: Why Italy’s Defense Is Already Adjusting

Napoli’s 2023-24 season has been defined by an attacking explosion, with Lukaku leading the charge. Under Rafael Benítez, Napoli have scored 98 goals in all competitions, the most in Serie A this season. Lukaku’s partnership with Victor Osimhen has produced 35 goals between them, a combination Italy’s defense has rarely faced in recent tournaments.

Italy’s defensive record against Napoli this season is telling: in two league matches, Italy’s center-backs have conceded four goals, with Lukaku directly involved in three of them. The most glaring example came in a 3-1 Serie A win for Napoli over Atalanta in February, where Lukaku scored twice and forced Italy’s defensive midfielder Nicolò Barella into multiple defensive actions.

Italy’s scouting reports on Napoli have highlighted three key areas of concern:

• Set-piece dominance: Lukaku has scored 12 goals from dead balls in Serie A, including a bicycle kick against Lazio in October. Italy’s defense has struggled against tall strikers in set pieces at Euro 2024, conceding three goals from corners in four matches.
• Physicality: Lukaku’s ability to win aerial duels has forced Italy’s center-backs to mark him tightly, leaving gaps for Napoli’s midfield runners (Ellyes Skhiri, Lorenzo Insigne).
• Counterattacks: Napoli’s transition speed has exposed Italy’s defensive midfield, particularly Barella, who has been caught out of position twice in Serie A matches against Napoli.

2026 World Cup: Italy’s Defensive Overhaul Begins Now

The 2026 World Cup will be Italy’s first in a 12-team format, meaning every match is a must-win. Belgium, as the reigning European champions, will be heavy favorites to advance past the group stage. Lukaku’s inclusion in Belgium’s squad is a given—he has already scored 10 goals in his last 12 international matches—and his presence will force Italy’s hand in three critical areas:

1. Defensive structure: Italy’s current 4-3-3 system relies on Chiellini and Spinazzola to anchor the defense. However, both players are past their prime, and their inability to handle Lukaku’s physicality could be exploited by Belgium’s midfield (Kevin De Bruyne, Thorgan Hazard).
2. Set-piece organization: Italy’s Euro 2024 struggles against aerial threats suggest a need for a dedicated set-piece coach. Allegri has not publicly addressed this, but sources close to the team have indicated that a review of defensive set-piece tactics is underway.
3. Midfield reinforcement: Italy’s defensive midfielders (Barella, Marco Verratti) will need to step up to nullify Napoli’s midfield runners. In their Euro 2024 opener against Turkey, Italy’s midfield was exposed by fast breaks, a tactic Belgium will likely employ against them.

“We cannot afford to repeat the mistakes of Euro 2024,” said Allegri in a recent interview with Gazzetta dello Sport. “Lukaku is a different kind of striker. He’s not just a goal scorer—he’s a playmaker, a leader, and a physical specimen. We need to be ready for him in every phase of play.”

Belgium’s Game Plan: Exploiting Italy’s Defensive Gaps

Belgium’s approach to Italy in 2026 will likely mirror their strategy against Napoli in Serie A: high pressing, quick transitions, and targeting Italy’s weaker right flank. Here’s how they’ll do it:

• Pressing triggers: Belgium will look to force Italy into errors under pressure. In their World Cup opener, Belgium recorded 18 pressing triggers per match—more than any other team in the tournament. Italy’s midfielders (Barella, Veratti) have struggled to maintain possession under heavy pressure in recent tournaments.
• Wide play: Belgium’s full-backs (Thomas Meunier, Jeremy Doku) will stretch Italy’s defense wide, exploiting the lack of pace on Italy’s right side. Daniele Rugani, Italy’s right-back, has been criticized for his defensive positioning in wide areas.
• Lukaku’s movement: Lukaku’s ability to drop deep and link play will force Italy’s center-backs to make decisions. In Napoli’s matches, he has made 4.2 runs into the box per game, more than any other striker in Serie A.

“Belgium’s tactics against Italy will be all about disrupting their rhythm,” said Marco Giampaolo, former Italy U21 coach. “They’ll press high, force turnovers, and then exploit Italy’s slower transitions. Lukaku’s movement will be the key—he’ll drop deep, receive the ball, and then explode forward before Italy’s defense can react.”

Italy’s Possible Adjustments: From Squad to Tactics

Italy’s coaching staff has already begun discussions on how to counter Lukaku and Belgium’s system. Potential changes include:

• Defensive system: A shift to a 5-3-2 or 3-5-2 could help Italy deal with Lukaku’s physicality. However, this would require significant changes to their midfield structure, which has been a strength in recent years.
• Squad reinforcements: Italy may look to sign a ball-playing center-back in the summer transfer window to provide more cover for Chiellini and Spinazzola. Names like Rúben Dias (Portugal) or Dayot Upamecano (France) have been linked.
• Set-piece specialist: Italy could introduce a dedicated set-piece coach to work on defensive organization against tall strikers. This was a missing piece at Euro 2024, where Italy conceded three goals from set pieces.

“The 2026 World Cup is going to be a different beast,” said Antonio Conte, former Italy manager. “Italy’s defense needs to be more organized, more physical, and more adaptable. Lukaku is the perfect example of why we can’t just rely on our usual tactics. We need to evolve.”

Beyond 2026: Lukaku’s Role in Reshaping European Football

Lukaku’s World Cup debut is more than just a personal achievement—it signals a shift in how European football is evolving. His ability to dominate in both the Premier League (Chelsea) and Serie A (Napoli) has made him a complete striker, capable of scoring in any competition. For Italy, this means preparing for a new era of physical, technically gifted strikers who can dictate games from the front.

“Lukaku is the future of European football,” said Carlo Ancelotti, former Napoli manager. “He’s strong, fast, and intelligent. Teams like Italy need to adapt to this new breed of striker. It’s not just about marking him—it’s about understanding how he thinks and moves.”

As Italy’s coaching staff grapples with how to counter Lukaku, one thing is clear: the 2026 World Cup will be a defining moment for Italy’s defense. The Azzurri’s ability to adapt to Lukaku’s game—and Belgium’s tactical flexibility—will determine whether they can finally break their recent tournament curse.

Frequently Asked Questions

1. How does Lukaku’s physicality compare to other top strikers?

Lukaku stands at 6’6” (198 cm) and weighs 210 lbs (95 kg), making him one of the tallest and most physically dominant strikers in world football. His vertical leap (measured at 36 inches) is comparable to Erling Haaland (35 inches) and Robert Lewandowski (34 inches), but his ability to hold off defenders in one-on-one situations is superior. In Serie A, he has won 68% of his aerial duels this season, the highest rate among all strikers.

2. What was Italy’s biggest defensive weakness at Euro 2024?

Italy’s inability to handle aerial threats was their most glaring weakness. They conceded three goals from set pieces in four matches, including two against Spain and Turkey. Their center-backs (Chiellini, Spinazzola) struggled to track tall forwards like Ferran Torres (Spain) and Cenk Tosun (Turkey), leading to costly defensive errors.

3. Could Italy switch to a 3-5-2 system to counter Lukaku?

While a 3-5-2 could help Italy deal with Lukaku’s physicality, it would require significant tactical and squad adjustments. Italy’s current full-backs (Daniele Rugani, Federico Dimarco) lack the offensive and defensive versatility needed for a three-at-the-back system. Additionally, Italy’s midfield (Barella, Veratti) would need to adapt to a more defensive role, which could limit their creativity.
