England are facing their toughest test of World Cup 2026 yet, and it comes 2,240 metres above sea level at the Estadio Azteca, where Thomas Tuchel’s Three Lions take on co-hosts Mexico in a last-16 tie that already feels like a final.

The road here has been anything but smooth. England survived a monumental scare to get past DR Congo 2-1 in their first knockout game. The Leopards stunned them early when the effervescent Brian Cipenga capitalised on shoddy defending to put Congo ahead, and Lionel Mpasi then produced an inspired goalkeeping display to keep England out. It took until the 30th minute for the Three Lions to even register a shot on target, their longest wait in a World Cup match to date.

With 15 minutes left, who else but Harry Kane stepped up. The captain scored a devastating double to turn the game around and send England through. It was a ‘job done’ win rather than one that enhanced their favourites tag, but it kept the tournament alive.

Mexico, by contrast, have been imperious. Javier Aguirre’s El Tri continued their impeccable run with a straightforward 2-0 win over a below-par Ecuador. Julian Quinones, who scored the first goal of the tournament as a whole, struck Mexico’s first of the knockout rounds before turning provider for Raul Jimenez to seal it.

That result did more than just put Mexico into the last 16. It exorcised 40 years of demons. The victory snapped an eight-game losing run in World Cup knockout matches, the longest such streak ever, and gave Mexico a post-group-stage win for the first time since that famous 1986 tournament at the same Azteca.

The numbers behind Mexico are formidable. Four wins from four in this World Cup, zero goals conceded, six wins in a row in all competitions, and a 12-match unbeaten run since a 2-1 friendly loss to Paraguay in November.

And then there’s the Azteca factor. Mexico have never lost a World Cup game at this ground, with eight wins and two draws from 10 matches. Their overall unbeaten streak across competitive and non-competitive games at the Azteca now stands at 26, dating back to a 2013 loss to Honduras. In total, they have lost just two of 89 competitive games at the 80,000-capacity stadium, the largest in Latin America. Their current run stands at 22 competitive matches unbeaten there, with 16 wins and six draws.

England know all about the history. This is their first return to the Azteca since that infamous 1986 quarter-final defeat to Argentina on Diego Maradona’s playground. The altitude, the noise, and the history make it feel like climbing Everest.

Head-to-head history offers some comfort for England. The Three Lions have won each of the last four meetings with Mexico, though the two sides haven’t met since 2010 when Glen Johnson, Ledley King and Peter Crouch scored in a friendly. That was a different era, and this is a different Mexico.

Team news adds another layer. Mexico look to have a clean bill of health and will have a full-strength squad roared on by a home crowd. England have bigger concerns. Declan Rice is a major doubt with a fitness issue, while there is better news with Reece James in line to return to the starting XI.

Tactically, this will test everything Tuchel has built. Against Congo, England were slow to find rhythm and vulnerable on transitions. Against Mexico in Mexico City, with the air thin and the tempo high, there is no margin for error. Kane will again carry the goal burden, but England will need much quicker ball circulation and better defensive concentration if they are to cope with Quinones and Jimenez, who are both in form.

For Mexico, the belief is sky high. They’ve beaten Germany already in this tournament and have dispatched Ecuador with ease. Playing at altitude, in front of their own fans, with a defence yet to concede, they will feel this is their moment to go deeper than ever before.

For England, it’s about composure under pressure. Surviving Congo showed resilience. Surviving the Azteca would show they are genuine contenders.

Kickoff in Mexico City will feel less like a last-16 tie and more like a statement game for both sides. One team’s unbeaten home fortress is on the line, the other’s status as favourites is too.

The match is scheduled for 6pm on Sunday in Mexico City, which is 1am on Monday in London and 3am on Monday in East Africa.
