When Mikel Merino stepped onto the pitch against Belgium, Spain needed a moment of inspiration.
Less than two minutes later, he delivered it.
The midfielder's
88th-minute winner sealed Spain's place in the FIFA World Cup semi-finals and underlined one of the defining tactical trends of the 2026 tournament: matches are increasingly being won by the players who don't start them.
Merino had already proven his worth from the bench in Spain's Round of 16 victory over Portugal. Against Belgium, he repeated the feat, becoming yet another substitute to influence a knockout game at a World Cup where fresh legs have often proved just as valuable as world-class starters.
The numbers behind the FIFA World Cup trend
Substitutes have scored 52 of the tournament's 250 goals so far, accounting for 18.6% of all goals scored.
That figure is just shy of the World Cup record of 18.7%, set at the 2014 tournament, highlighting how influential benches have become in modern international football.
The trend becomes even more striking when looking at goals scored in added time.
A record 11.4% of all goals at the 2026 World Cup have come during stoppage time, the highest proportion in tournament history.
Even more telling, 53% of those injury-time goals have been scored by substitutes.
Rather than merely adding energy, managers are increasingly introducing players specifically to exploit tiring opponents in the closing stages.
Spain show the blueprint
Spain have perhaps demonstrated this strategy better than anyone.
Against Portugal, Merino came off the bench to help decide the contest. Against Belgium, he needed barely two minutes to score the decisive goal after entering late in the match.
Luis de la Fuente has repeatedly trusted his squad depth, knowing fresh attacking players can stretch defensive lines that have spent over an hour chasing possession.
Rather than relying solely on their starting XI, Spain have turned their substitutes into genuine match-winners.
Norway's bench changed everything against Brazil
Norway's famous victory over Brazil followed a similar script.
Andreas Schjelderup replaced Antonio Nusa at half-time and completely changed the game's rhythm.
The Benfica winger provided both assists for Erling Haaland as Brazil's defence struggled to deal with his direct running and creativity in the second half.
It was another reminder that knockout football is often decided by tactical adjustments rather than opening line-ups.
## Sometimes it is mentality, not substitutions
Not every dramatic finish has been driven by changes from the bench.
Argentina's extraordinary comeback against Egypt came largely through belief, composure and relentless pressure.
Trailing 2-0 entering the final stages, Lionel Scaloni's side mounted a stunning fightback through Cristian Romero, Lionel Messi and Enzo Fernández before eventually winning 3-2.
It showed that while substitutes can change matches, elite teams also possess the mentality and fitness to overwhelm opponents late on.
Why are more matches being decided late?
Modern football demands constant pressing, rapid transitions and relentless intensity.
Maintaining those physical standards for more than 90 minutes is becoming increasingly difficult, particularly during a month-long tournament played in summer conditions across North America.
As fatigue sets in, defensive concentration drops, spaces appear between the lines and fresh attackers become far more dangerous than they would have been earlier in the game.
Managers are no longer simply using substitutions to replace tired players-they are actively planning for the final 20 minutes, treating their bench as an extension of their starting XI.
FIFA World Cup's biggest lesson
The 2026 FIFA World Cup has reinforced one simple truth: matches are no longer won solely by the best starting line-up.
Squad depth, intelligent substitutions and physical conditioning have become decisive factors, particularly in knockout football.
With more goals arriving in stoppage time than ever before and substitutes contributing at near-record levels, one trend has become impossible to ignore.
At this World Cup, the final whistle-not the 90th minute-is when matches are truly decided.
