Former England captain and Alan Shearer has declared himself a believer in England's FIFA World Cup ambitions, admitting he has changed his earlier opinion after the Three Lions' impressive Round of 16 victory over co-hosts Mexico.

Writing in his BBC column, the Newcastle United legend revealed that England's commanding display at the Estadio Azteca convinced him that the team has what it takes to lift the World Cup trophy.

Prior to the knockout clash, Shearer had questioned whether England possessed the quality and resilience needed to go all the way in the tournament. However, their performance against Mexico dramatically altered his perspective.

"There’s always hope with England at a major tournament, but that performance against Mexico has pushed us all further forward and given everyone, including me, confidence and belief too," Shearer wrote.

He added that before arriving at the Azteca Stadium, he did not genuinely believe England could become world champions, but their display changed his mind completely.

"I didn’t truly believe England could win this World Cup, but I have changed my mind, and I think everyone else has too," he said.

England's victory has set up a quarter-final showdown against Norway national football team, with the Three Lions looking to continue their impressive run in the tournament.

The comments from England's all-time leading Premier League goalscorer reflect the growing optimism surrounding the national team, whose performances have gathered momentum as the competition has progressed.

With confidence building among supporters and former players alike, England will head into the quarter-finals carrying increased expectations as they pursue their first World Cup triumph since 1966.

Opinion: Belief Can Be as Important as Talent

Alan Shearer's change of heart mirrors the emotions of many football fans during major tournaments. Early doubts can quickly disappear when a team produces a convincing performance against strong opposition.

England's victory over Mexico appears to have done more than secure qualification—it has restored belief. In tournament football, confidence often becomes one of the most valuable assets, giving players the courage to perform under intense pressure.

However, Shearer's optimism should also be tempered with caution. Winning a World Cup requires consistency over several knockout matches, and England still face formidable opponents beginning with Norway.

If the Three Lions can maintain the level of discipline, composure and attacking quality they displayed against Mexico, they will have every reason to believe they can challenge for the title. But as history has repeatedly shown, momentum alone does not guarantee success. The toughest tests are often still to come.
