Forty-eight teams. Twenty-four matches. One round of group-stage fixtures complete, and the Opta numbers are already telling a different story than the scoreboards. Argentina’s 2-1 win over Iceland looked routine until the expected-goals model spat out 3.8 to 0.4 in the champions’ favour, the most lopsided xG margin of the tournament so far. Saudi Arabia, beaten 1-0 by Norway, generated more shots on target (seven) than Spain managed against Cape Verde. And a 17-year-old Ecuadorian midfielder has already completed more progressive passes than Kevin De Bruyne. The opening week has rewarded the patient observer and embarrassed anyone who watched only the highlights.
Expected goals: who flattered, who deserved more
The widest xG-to-result gap belongs to Mexico, who beat South Korea 2-0 in Guadalajara despite an xG of just 0.7 against the Koreans’ 1.9. Hirving Lozano’s deflected 71st-minute strike — assigned a post-shot xG of 0.04 — was the kind of goal that wins tournaments and breaks models. At the other end, Belgium drew 1-1 with Canada having out-chanced their opponents 2.6 to 0.5, with Romelu Lukaku missing two openings Opta valued at a combined 0.71 xG. He has now failed to score in his last six World Cup knockout-or-group matches.
Brazil’s 4-0 dismantling of Morocco looked emphatic, and the underlying data confirmed it: 3.1 xG, 21 shots, and a pressing intensity (PPDA of 7.4) that ranked second only to Germany’s display against Japan. Vinícius Júnior alone created six chances, equalling the single-match record set by Lionel Messi against Mexico in 2022. Spain, by contrast, were fortunate to escape with a 1-1 draw against Cape Verde: an xG of 0.9 against the islanders’ 1.4, and only Unai Simón’s three saves — including a 94th-minute reflex stop from Ryan Mendes — kept Luis de la Fuente’s side from a defeat that would have triggered immediate inquest at home.
The individuals reshaping perception
Kendry Páez, the 17-year-old Chelsea-bound midfielder, completed 47 progressive passes in Ecuador’s 1-1 draw with Ivory Coast — more than any player at the tournament and 12 more than De Bruyne managed for Belgium. Of those 47, 31 came in the opposition half. For context, only three midfielders in the entire 2022 tournament averaged more than 35 per match across the group stage: Luka Modrić, Jude Bellingham and Enzo Fernández.
Other numbers worth holding on to:
- Erling Haaland’s expected goals per 90 in Norway’s win over Saudi Arabia: 1.42, the highest single-match figure since Opta began tracking the metric at World Cups in 2010.
- Cole Palmer’s progressive carries against Serbia: 14, more than the entire France midfield combined (11) in their defeat of Iran.
- Endrick’s shot conversion rate so far: 100% (two shots, two goals), though his combined xG of 0.38 suggests regression is coming.
- Mohammed Kudus’s chances created against Colombia: nine, the most by an African player in a single World Cup match this century.
The transfer-value lens flatters and disappoints in equal measure. Tunisia’s starting XI against Denmark — combined market value of €31m on CIES data — held a French-coached Danish side worth €612m to a single goal until the 89th minute. Lassine Sinayoko, whose €4m valuation makes him the cheapest forward at the tournament, scored Mali’s equaliser against the Netherlands with their only shot on target.
What it means for matchday two
Three patterns matter. First, the high-press sides — Germany, Brazil, Portugal — are generating turnovers in the final third at roughly 1.4 times the rate of any squad in Qatar 2022, suggesting the increased squad sizes (26 has become 27 in 2026) are letting managers rotate without losing intensity. Second, the goalkeeping data is unusually flat: post-shot xG minus goals conceded shows only three keepers (Simón, Mike Maignan, Yann Sommer) significantly over-performing, against eight at the same stage four years ago. The penalty area is becoming a more honest place.
Third, and most consequential for the bracket: of the eight teams who recorded a negative xG difference but still won their opener, six face stronger opponents next. Mexico travel to play Brazil. Switzerland meet Germany. Cameroon take on Argentina. The models say the regression is coming. Lionel Scaloni, asked in Dallas whether his Argentina side were taking anything for granted, answered with the look of a man who had read the underlying numbers. “We were lucky against Iceland in only one sense,” he said. “The score.” On the evidence of round one, he was right.
