Iceland have just done it. They really have.This is just such a big result, such a seismic one for the footballing world. Of course, the players have shown they are very good at what they do. But still, we're talking about a country of 330,000 people. Against a heavyweight like England and its population of 53 million. It's indescribable. People outside the country will struggle to grasp quite how much it means. Supporters filled the city centre in Reykjavik. Thousands and thousands showed up to watch the game. You can possibly imagine the atmosphere was there at the final whistle.
