Cinemas throughout the country will be screening the game, and any non-football fan visiting the beautiful city of Barcelona may find getting around difficult.

This is Barca v Madrid and this fixture's history is saturated with incidents.

Madrid-loving dictator Francisco Franco; the transfer of Alfredo di Stefano from Barca to Real; the controversial 1961 European Cup semi-final when Madrid felt they had been cheated out of a penalty. Just the tip of the iceberg.

More recently, of course, was the famous flying pig head at the Nou Camp launched at Luis Figo, returning to his old club with Real Madrid. It is the reason that plastic nets are still erected behind the goals at the Nou Camp.

That said, the rivalry has always been about which is the best team in Spain.

There have been moments in the last decade where Deportivo La Coruna, Valencia and Sevilla have perhaps challenged for that title.

But in truth it is Barcelona and Real who have dominated not only in Spain but in Europe and are among the richest clubs in the world.

With the purchases of Cristiano Ronaldo and Kaka in the summer, Real spent a cool £140m, while Barca, in theory, spent upwards of £70m on Ibrahimovic in exchange for Samuel Eto'o and several extra millions.

Between them, the two clubs have won the Spanish title seven times since the turn of the century, and that trend seems unlikely change this season. They have also collected four Champions League titles this decade.

Real go to the Nou Camp leading the title race by just one point. Can they stretch their lead over Barca to four come Sunday evening?

At least four players from each team are capable of changing the game in an instant - namely Messi, Iniesta, Pedro and Xavi for Barcelona and Ronaldo, Higuain, Kaka and Casillas for Real Madrid.

One of these could well be the hero on the front pages of newspapers and magazines around the globe come Monday.
