Shortly before England's World Cup last-16 match against Mexico, a group of home supporters gathered near the team hotel in Mexico City, chanting, playing music and letting off fireworks into the early hours. Their aim: to disturb the sleep of the England players and give their own team a competitive edge. But early indications from the England camp suggested the disruption had minimal impact, and police in riot gear quickly moved the fans further away.
This is a tactic known as fan disruption, where supporters of the host nation—or sometimes rival fans—attempt to unsettle the visiting team by targeting their rest. The idea is that sleep deprivation can impair performance, slowing reaction times and reducing concentration. While such behaviour is not official policy, it has been seen at major tournaments, especially when the host nation's fans are particularly passionate. In this case, the Mexico supporters were reportedly inspired by Ecuador, who earlier lodged a noise complaint with world governing body Fifa after similar disruptions—including loudspeakers, motorbikes and horns—kept their players awake ahead of their match against Mexico.

For UK readers, the incident is a reminder of the extreme lengths fans sometimes go to in support of their national team. Many England fans themselves were preparing for a sleepless night watching the match, with experts warning of a "national hangover". Dr Sally Adams, a hangover expert at Birmingham University, said the combination of drinking, lack of sleep and sporting stress could make the day after one of the "top three hangover days of the year". Employers were urged not to assume a no-show was due to the match, and schools were told not to punish pupils for bad attendance. The "hangxiety"—a mix of hangover and anxiety—could affect millions, with an estimated 4.8 million workers potentially bunking off or arriving late.
Q: Is this type of fan disruption a common tactic at World Cups? It has been used before, particularly by host nations. Before this match, Ecuador complained about noise from Mexico fans, and similar incidents have occurred at other tournaments. However, it is not universal, and many host nations have friendly atmospheres.
Q: Does sleep disruption actually affect player performance? Yes, research suggests that poor sleep can impair decision-making, reaction times and attention. But England's manager Thomas Tuchel said the team's treatment in Mexico had been "nicer" than expected, and the early feedback was that the disruption had minimal impact on the players.
Q: What can officials do to prevent these tactics? Police can increase security around team hotels and move disruptive fans away, as happened here. Fifa can also issue warnings or sanctions against national associations if the behaviour is deemed excessive.
What happens next is uncertain. The match at the Azteca Stadium was scheduled for Sunday evening local time, with England aiming to progress to the quarter-finals. Regardless of the result, the debate over fan disruption is likely to continue, especially if such tactics are seen again in future tournaments.
