Former Barcelona star Gaizka Mendieta says that the clash against Real Madrid, El Clasico, is the biggest football game in the world. Mendieta: "Well, it's more than just that day, the build-up is a week or even weeks earlier than El Clasico. It is a game which is marked in the calendar at the beginning of the season. Not only Barcelona fans or Real Madrid fans, but football fans in general. That day is definitely marked in the calendar. As a football player, I was lucky to be involved in other big games, but this is the biggest in world football. It is a privilege to have had the opportunity to be part of. It is very special because everyone speaks about it; the media does, your family does, people on the street do as well… and if you have great players like Barcelona and Real Madrid always have, it is even bigger."
