Real Madrid vs. Barcelona, Cristiano Ronaldo vs. Lionel Messi. El Clasico is a game that is guaranteed to have the eyes of the football word upon it and nothing else seems to matter when these two Spanish behemoths collide.
It is, arguably, the biggest club game in the world and is watched by a worldwide audience in the multi-millions.
Only the Champions League final can rival it's appeal and the fixture, especially in the last few years, has rarely let us down.

Let's recall three El Clasico games from the annals of the fixture's rich history...
3-3 - March 2007
A six-goal thriller to mark Lionel Messi's debut in the fixture, three of which were scored by a then 19-year-old Messi.
Ruud Van Nistelrooy's two-goal blast inside the first 12 minutes probably had everyone thinking that Real would wrap this one up before half time.
They obviously reckoned without the Argentinian genius who had Barca back on level terms before the break in front of 99,000 screaming Blaugrana supporters.
Sergio Ramos' 72nd minute goal against 10-man Barca looked to have sealed the game until Messi popped up in injury time to send the home crowd into rapture once more.
6-6 - January 1916
The equal highest scoring El Clasico to date took place almost 100 years ago. It also remains unique in the history of this glorious fixture as it featured three hat-tricks in the same game.
A game that was a first replay of the first round of the Copa Del Generalisimo, the forerunner of the Copa Del Rey.
The match went all the way to the end of extra time, and it still took a further replay to finally split the teams.
Santiago Bernabeu and Belaunde were both on target three times for the hosts with Barca replying via a hat-trick from Paulino Alcantara - the club's record scorer until Messi came along - and one each from Bau, Mallorquí, Martínez.
11-1 June 1943
The other 12-goal Clasico is one that Real Madrid don't celebrate too much. Which is odd when you consider that they were the victors. The second leg of the semi-final of the Copa Del Generalisimo was a farce.
Barcelona had soundly beaten their greatest rivals by three goals to nil in the first leg and the second should really have been a formality.
The Catalans found themselves 8-0 down by half time - Pruden (5, 32,35), Barinaga (30, 42, 44), Alonso (37) and Curta (39).
Alonso (74), Botella (85) and Baringa (87) added three more in the second half, with Barca's consolation not arriving until the last minute via Martin.
Barcelona players were allegedly intimidated by police and the hostile atmosphere was like nothing ever experienced in the fixture before or since.
It remains Real's record win in any game.
