Mexico. The sheer passion and love for their team and football was incredible. Also such friendly, welcoming fans and people. Incredibly warm and gracious in defeat.
We were in a restaurant in Mexico City the night before they played England, and an MC went around each table asking which country people were from. When we told them we were from England, it was announced to the rest of the diners, who burst into a spontaneous outbreak of applause.

A word for the Curacao fans I was with inside the Philadelphia Stadium – because who knew that supporters from a nation of just 150,000 could make that much noise? Was there anyone left on the island? But the Brazil fans win it for me because they do not just take over stadiums; they take over cities; Philadelphia felt like Rio or Sao Paulo for 48 hours when they were in town.

The Colombia fans took over Arrowhead Stadium in Kansas City when they played Ghana, and made it feel like a party.

Norway’s fans were brilliant, with their legendary Viking row taking over the World Cup. The chant became a global sensation and created an unforgettable atmosphere in every stadium they entered. The most iconic moments came after matches when the players joined the fans to lead the Viking row from the pitch, uniting thousands of supporters in celebration.

I was based mainly in Los Angeles for the World Cup. There’s a large Mexican population there and from what I experienced, they were undoubtedly the best supporters. They were loud – very loud – for every Mexico game and when they won fireworks could be heard around LA while their distinct green jerseys were seen everywhere.

Norway’s Viking row was fun to watch, with fans wearing red shirts sitting in lines and rowing in rhythm. The Norway supporters also provided an amusing moment during the quarter-final with England. They sang “You’re going home, you’re going home, England’s going home” as they led 1-0 in Miami. Moments later Jude Bellingham equalised.

The Mexicans. I was fortunate to experience two matches in the Azteca. That is where the heart of this World Cup was and the support for their team was a joy to behold.

Argentina. On two occasions in Miami and Kansas City, I have been in stadiums where their support has been in excess of 60,000 fans. The sheer scale of numbers is matched by their wild passion. They sing constantly and have generated the best atmospheres I have encountered in the US.
