World Cup final: Spain's defensive record against Argentina's xG surge

Spain and Argentina will contest the World Cup final on Sunday, the first final in the tournament's history to pit the champions of Europe against the champions of South America. The fixture also brings together the top two teams in FIFA's world ranking of men's international sides.

Opta's supercomputer rated Luis de la Fuente's Spain as favourites to lift the trophy, while Argentina — the reigning champions — were listed as only fourth likeliest. Both that model and the wider statistical picture placed England and France in the top four, which aligns with the semi-final line-up.

What the numbers say

The central contrast ahead of kick-off is stylistic. Spain have built their run on an outstanding defensive record, limiting opponents' clear chances across the tournament. Argentina, by contrast, have scored at a rate that outstrips their expected goals (xG) — a measure of the quality of the opportunities they have created rather than the goals actually scored.

That gap between xG and output is the question hanging over the final. If Argentina's finishing continues to exceed the underlying numbers, they can punish a Spain side that has conceded little; if it regresses towards the expected level, Spain's defensive solidity becomes the decisive factor.

• Spain and Argentina are first and second respectively in FIFA's men's world ranking
• Opta's supercomputer made Spain tournament favourites, with Argentina rated fourth likeliest
• England and France featured in the top four of both forecast systems, matching the semi-finalists
• Argentina, the reigning champions, have been outperforming their expected goals
• Spain's defensive record is the standout statistic behind their run to the final

Why it matters

For Spain, the final is a chance to convert a dominant statistical profile into a first world title since 2010 and to justify the models that installed them as front-runners from the knockout stages onward. For Argentina, victory would mean back-to-back World Cups and a defence of the trophy achieved against the side the data ranks above them.

Sunday's result will also shape how these forecasting tools are read in future tournaments: whether defensive control or clinical finishing above expectation proves the more reliable route through a knockout competition. The answer arrives at full time.
