The 2025-26 season proved beyond doubt that this was Nico O’Reilly’s breakout campaign. The Manchester City talent carried his impressive form from the conclusion of the 2024-25 season into a role as a key player for his club. This progression earned him a place in England’s World Cup squad. As England advances to the tournament’s semi-final stage, O’Reilly has played a vital role for his country. While teammates like Harry Kane and Jude Bellingham have naturally dominated the headlines, O’Reilly’s contributions at left-back have been essential to the World Cup run orchestrated by manager Thomas Tuchel.

Nico O’Reilly has been a steady presence for England at left-back at the World Cup.

England has managed various defensive injury challenges throughout their World Cup campaign. Newcastle United full-back Tino Livramento was sidelined by injury just before the tournament, leading to his withdrawal and replacement by Trevor Chalobah. Furthermore, Reece James and John Stones have navigated injury setbacks, while Jarrell Quansah served a two-match suspension following a red card in England’s 3-2 victory against Mexico during the Round of 16. These absences forced Thomas Tuchel to experiment with right-back solutions, while Nico O’Reilly has provided a steady, quiet impact at left-back.

O’Reilly has started five of England’s six matches, delivering performances that perfectly match Thomas Tuchel’s tactical requirements. His defensive solidity, bolstered by his size and athleticism, has been a significant asset. Although he has yet to score, the Manchester City youngster frequently contributes to the attack. Given his history of performing in high-pressure moments, a decisive goal against Argentina in the semi-final would not come as a surprise. A major test awaits O’Reilly, and he will need to be fully prepared for the challenge.

Lionel Messi and Argentina await England and the Manchester City left-back will face a tough task in the semi-final tie.

England faces their traditional rivals, Argentina, in the second semi-final of the World Cup. Thomas Tuchel’s squad aims to avoid the tournament exits experienced by previous England teams in 1986 and 1998. Standing in their way is a battle-hardened Argentina side led by Lionel Messi, who has recorded eight goals so far in the competition. To reach the World Cup final, England must find a way to contain Messi, a task in which Nico O’Reilly will likely play an important part.

Lionel Messi operates in a free role in the final third for Argentina, choosing specific moments to exert his influence. He often cuts inside from the right to create dangerous opportunities. Should the Argentine legend utilize this tactic, the responsibility will fall largely on Nico O’Reilly—with assistance from his teammates—to neutralize him. The Manchester City youngster clearly understands the scale of the challenge, but his temperament and physical attributes suggest he is well-equipped for the task.
