Lionel Messi deserves England's full attention — anything less could cost Thomas Tuchel a place in the World Cup final.

England's biggest tactical question ahead of the FIFA World Cup 2026 semi-final isn't about formation or personnel. It's about how to stop Lionel Messi. Former Watford captain Troy Deeney believes Thomas Tuchel has a straightforward solution: assign someone to stay with the Argentina captain far more closely than previous opponents have managed.

The debate gathered momentum after Argentina booked their place in the semi-finals with Messi again playing a decisive role. While the 39-year-old no longer covers every blade of grass, his influence remains enormous whenever Argentina move into the attacking third. Deeney argued that too many teams have allowed Messi to drift into dangerous pockets without sustained pressure, describing the freedom he has enjoyed as "getting away with murder" during a discussion on talkSPORT.

England's Biggest Tactical Dilemma Isn't Formation — It's Messi

England have impressed throughout the tournament under Thomas Tuchel, balancing defensive organisation with attacking efficiency. Yet facing Argentina presents a challenge unlike any they've encountered so far.

Messi doesn't need dozens of touches to dominate a match. He waits. He scans. Then, in one movement, he turns a harmless possession sequence into a defence-splitting attack.

That's exactly why Deeney believes England cannot rely solely on their existing defensive structure.

Rather than asking different midfielders and defenders to pick up Messi as he enters their zone, Deeney suggested England should consider giving one player primary responsibility for staying close to the eight-time Ballon d'Or winner whenever Argentina have possession. The idea isn't traditional man-marking for 90 minutes, but a far more aggressive approach than many of Messi's recent opponents have attempted.

"He's getting away with murder because nobody stays with him."

Here's the part nobody's saying out loud: England don't necessarily need to stop Argentina. They need to stop the moments when Messi decides the match.

The Evidence Behind Deeney's Argument

Supporters of Deeney's view point to a pattern that has followed Messi throughout the tournament. Opponents have generally prioritised maintaining defensive shape rather than disrupting Messi before he receives the ball.

That decision comes with obvious risks.

Once Messi turns to face goal, defenders are already reacting rather than preventing danger. His vision, close control and passing range allow Argentina to progress quickly, even if he isn't sprinting past defenders as frequently as he did earlier in his career.

England possess disciplined midfielders capable of tracking runners, but Messi rarely behaves like a conventional No.10. He drifts between lines, moves into half-spaces and often begins attacks from surprisingly deep positions before accelerating into dangerous areas.

Those movements make him exceptionally difficult to contain using a purely zonal system.

Even so, assigning one player to shadow Messi carries its own dangers. If England commit an extra midfielder to following him everywhere, Argentina's other attacking players could exploit the spaces left behind. That's precisely the balance Thomas Tuchel must judge before the semi-final.

Officially, Tuchel has consistently backed England's collective defensive approach throughout the tournament, stressing organisation over individual assignments. Yet Deeney's criticism forces an important question: does collective discipline alone work against the greatest playmaker of his generation?

The answer could determine who reaches the FIFA World Cup 2026 final.

Counter-Argument: Why Thomas Tuchel May Resist Man-Marking Messi

Tuchel's coaching philosophy has rarely revolved around assigning one player to follow an opponent across the pitch. Whether at Borussia Dortmund, Paris Saint-Germain, Chelsea or Bayern Munich, his teams have typically relied on coordinated pressing, compact defensive lines and intelligent positioning instead of old-fashioned man-marking.

That's the strongest argument against Deeney's proposal.

A dedicated marker can become a liability if Messi deliberately drops into midfield or drifts towards the touchline. Following him everywhere risks pulling England's defensive shape apart and creating space for Argentina's supporting cast, including Julián Álvarez and Enzo Fernández, to exploit.

History also suggests that simply shadowing Messi doesn't guarantee success. Numerous elite managers have attempted similar plans over the years, only for Argentina's captain to influence matches through clever movement, quick combinations or decisive moments from set pieces.

Still, Deeney's broader point carries weight. England cannot afford to give Messi the same freedom that previous opponents have allowed. The challenge isn't necessarily to man-mark him for 90 minutes but to ensure he is immediately pressured whenever he receives possession between the lines.

That hybrid approach—maintaining England's structure while aggressively closing down Messi's space—may offer the best compromise.

Why This Debate Could Decide The Semi-final

England have shown throughout the tournament that they can defend as a unit, remain patient without the ball and punish opponents in transition. Those qualities have carried them to within one victory of a World Cup final.

Argentina, however, present a different examination. Their attack still revolves around Lionel Messi's ability to dictate tempo, attract defenders and unlock compact defensive blocks with one pass or one touch.

That's why Deeney's comments have resonated beyond television debate. They challenge England to consider whether their existing defensive principles are enough against a player whose influence often transcends tactical systems.

Tuchel is unlikely to abandon the structure that has brought England this far. Instead, expect carefully coordinated pressing triggers whenever Messi drops into dangerous pockets, with midfielders and centre-backs communicating constantly to deny him time on the ball.

Whether that proves sufficient remains the defining tactical storyline heading into the semi-final.

England don't need to stop every Argentina attack. They need to minimise the handful of moments when Messi can change everything. If they succeed, Tuchel's side will have every chance of reaching the World Cup final. If they don't, the greatest player of his generation may once again decide football's biggest stage.
