Mexico and England meet at Estadio Azteca on Monday morning UK time, with a place in the World Cup quarter-finals at stake.
Mexico arrive as one of only two teams to win all four matches without conceding a goal, while England needed a late Harry Kane brace to rescue their Round of 32 tie against DR Congo. The result sent Thomas Tuchel's side through, but the underlying numbers suggest England have been one of the tournament's strongest teams despite a less convincing scoreline.
Mexico's progress has been built on discipline, organisation and home advantage. Javier Aguirre's side topped Group A with maximum points before beating Ecuador 2-0 for their first World Cup knockout victory since 1986. The results have been outstanding, although the underlying numbers paint a more balanced picture.
Across four matches Mexico have generated 4.78 xG while conceding 2.26, producing an expected points total of 7.26 compared with their perfect return of 12. No remaining side has outperformed its underlying numbers by a wider margin, with only France posting a similar gap.
Julian Quinones and Raul Jimenez have provided the cutting edge, while Mexico's defensive record deserves enormous credit. Four clean sheets in four matches cannot be ignored, even if they have benefited from some fine margins along the way. Playing every match in front of passionate home support at altitude has also given Mexico one of the strongest environmental advantages in the tournament.
England have travelled a different path. Their 2-1 victory over DR Congo looked comfortable on paper, but the performance was anything but. They trailed entering the final 15 minutes and survived an early scare when Yoane Wissa struck the post before Harry Kane scored twice to rescue the tie. The result highlighted England's resilience, but it also masked what has been an outstanding tournament from an underlying perspective.
England have generated 8.28 xG across four matches, more than every remaining nation except France and Brazil. Their expected points total of 9.28 sits almost perfectly alongside their actual return of 10, suggesting performances have closely matched results. Where Mexico have consistently outperformed the numbers, England have simply produced them.
The longer-term data also favours Tuchel's side. England sit fourth in the latest World Football Elo rankings on 2046 points, more than 100 ahead of Mexico in ninth on 1943. Over a large sample England rate as the stronger team. The challenge is translating that advantage to one match played more than 2,200 metres above sea level against tournament hosts backed by more than 80,000 supporters.
How the bookies view it
Mexico are priced at 11/5 to win in 90 minutes, implying a 31.3% probability. The draw is 9/4, implying 30.8%, while England are 6/4, implying 40.0%. Over 2.5 goals is available at 7/5, implying 41.7%, while both teams to score is priced at 21/20, implying 48.8%.
My own Dixon-Coles model, adjusted for Mexico's home advantage and altitude, broadly agrees with the outright market. England remain slight favourites over 90 minutes, but the biggest difference comes in the goals markets. My model makes over 2.5 goals closer to a 20% chance and both teams to score around 30%, considerably lower than current prices. Mexico have yet to concede in the tournament, while knockout football historically becomes more cautious as the competition progresses.
Head to head: England dominate the history between the two nations
England have dominated this fixture historically. The sides have met nine times since 1959, with England winning six, drawing one and losing two while scoring 23 goals and conceding only four.
Mexico's victories both came at home, including a 1-0 win at Estadio Azteca in 1985. England have won each of the last four meetings, including a 3-1 victory at Wembley in 2010. Their only previous World Cup meeting came in 1966, when England won 2-0 on their way to lifting the trophy.
Player to Watch: Harry Kane the difference maker
Harry Kane has once again proved decisive when England have needed him most. His two late goals against DR Congo rescued a tie that was drifting away, taking him to five goals and one assist in four appearances at this tournament.
The underlying numbers support that return. Kane has generated 2.6 xG and 3.2 xGOT from 18 shots, nine of which have hit the target. He has also missed three big chances, so there is scope for his goal tally to grow further if England continue creating opportunities at their current rate.
Mexico have yet to concede in four matches, but they have not faced a striker with Kane's movement, aerial ability and finishing. His willingness to drop into midfield before attacking the penalty area creates problems that few international defences solve consistently.
If England are to end Mexico's remarkable defensive run, Kane is the player most likely to make the difference.
Predicted line-ups
Mexico 4-3-3: Rangel; Sanchez, Vasquez, Montes, Gallardo; Romo, Lira, Mora; Quinones, Jimenez, Alvarado.
England 4-2-3-1: Pickford; Spence, Konsa, Guehi, O'Reilly; Anderson, Rice; Madueke, Bellingham, Rashford; Kane.
Anything else catch the eye?
Under 2.5 goals stands out as the best bet.
Mexico have yet to concede in the tournament, recording four consecutive clean sheets while allowing only 2.26 xG across four matches. England's attacking numbers have been among the strongest in the competition, but they have also shown they can dominate possession without creating a constant stream of clear chances. Against DR Congo they managed only one shot on target before the closing stages despite controlling much of the game.
My Dixon-Coles model projects over 2.5 goals at only around 20%, considerably below the market expectation. The gap is driven by two disciplined defensive sides, the importance of the occasion and the historical trend of knockout matches becoming increasingly cautious as teams move deeper into the tournament.
The outright market looks about right once Mexico's home advantage and altitude are factored in. The goals market is where the value lies. A tight, tactical contest decided by one or two moments feels far more likely than an open game, making under 2.5 goals the standout selection.
