Alan Shearer has changed his mind about England's chances of winning the World Cup following their epic win over Mexico. He states that before the game, he didn't truly believe England could win, but the performance at the Azteca Stadium has given him confidence and belief. Shearer describes the display as the best team performance he has seen from any England side in his lifetime, particularly given the challenges of altitude, a hostile atmosphere, and playing with 10 men. Shearer highlights the contributions of every player, including the big-hitters like Harry Kane and Jude Bellingham, and praises manager Thomas Tuchel's substitutions. He draws a parallel to his own experience as a player at Euro '96 after beating the Netherlands 4-1. Shearer believes the team's adaptability is a key strength, and that whatever happens in a game, Tuchel's England will be ready for the challenge of playing Norway in the quarter-finals.
