‘Once-in-a-lifetime!’ — Nico O’Reilly Relishing the Messi Challenge as England Face Argentina in the World Cup Semi-Finals

Nico O’Reilly is 20 years old, and his next job is Lionel Messi. England meet Argentina in the World Cup 2026 semi-finals, and the Manchester City midfielder has called the assignment a “once-in-a-lifetime” opportunity. It is also, on current evidence, one of the hardest jobs in the sport. Jordan Pickford, meanwhile, has a warning for anyone who thinks stopping Messi is the whole plan.

O’Reilly vs Messi: the duel that could settle the semi-final

O’Reilly is expected to shoulder one of the toughest assignments in football: shadowing Lionel Messi for 90 minutes, possibly 120. The Manchester City youngster did not shy away from it, describing the challenge as a “once-in-a-lifetime opportunity”. At 20, facing the Argentina captain in a World Cup semi-final is the sort of night that defines a career — in either direction.

The cruel part is that Messi no longer needs to run to hurt you. He drifts, he waits, and he plays the pass nobody else saw. Man-marking can hold for twenty minutes. Beyond that, the space simply opens somewhere else on the pitch.

Pickford’s warning: Argentina are not just Messi

Jordan Pickford has been blunt with his teammates: do not build the entire game plan around one player. The England goalkeeper knows Argentina have a settled, ruthless collective that punishes the moment every eye drifts towards the No.10. Plenty of good sides have drowned making exactly that mistake.

It is the classic trap. Double up on Messi, leave the space in behind the full-backs, and Argentina cut you open on the counter. Pickford has been through enough tournaments to recognise the warning signs before the scoreboard delivers them.

What England must get right to reach the final

England’s route through this semi-final runs through midfield control. If the Three Lions can dominate possession in the middle third and force Argentina to defend deep, Messi sees less of the ball in dangerous zones and the whole problem shrinks. Concede that ground and the game becomes a series of one-on-one emergencies.

Set pieces matter too. England have historically found goals from dead-ball situations in knockout football, and in a tie this tight, one corner may be the difference between a final and a flight home.

Messi and the weight of a possible last dance

At this stage of the tournament, every Lionel Messi appearance could be his last in a World Cup. Argentina know it, and so do their opponents. That emotional weight lifts the Albiceleste and turns every individual duel into an event in its own right.

For a player like O’Reilly, born long after Messi made his international debut, this is close to a generational collision. That is precisely why he calls it a once-in-a-lifetime chance. Whether the memory turns out glorious or painful is the only question left.
