El Clasico is probably the most watched football derby in the world. Nowhere in the world so much is put on the line.

If you think Chelsea and Manchester City have the most expensive players and the biggest wage budget, you should really take a look at the numbers Real Madrid and Barcelona spend.

Without doubt, these two giants of Spain have squads unmatched in talent and extravagance. Europe fears running into either of the two.

The recent addition of Jose Mourinho to the ranks of Madrid has made this derby even more worthwhile. Prior to his inclusion, Pep Guardiola had made this a one-sided affair.

The 2011 Copa del Rey final was the first Madrid win over their rivals since 7th May, 2008 when Madrid won 4-1 at the Santiago Bernabeu. There have been seven El Clasicos since and the aggregate goals score has been 15-4 in favor of the Catalan giants.

As Madrid finally manage to progress in the UEFA Champions League this season, they have landed in a semifinal against Barcelona. Two more El Clasicos have already been played in a space of four days – Bernabeu leg of La Liga and Copa del Rey final.

Before these two, Madrid last played Barcelona at the Nou Camp which ended in a 5-0 pounding of Mourinho’s men – on 29th November, 2010.

Lets briefly analyze the tactics of the two games:

In the match in Valencia, José Mourinho once again opted for the defensive trivote of Xabi Alonso, Pepe and Sami Khedira from Saturday's match at the Bernabéu. As can be seen in the graphics, Real Madrid had several more shots in the cup final than they did in the 0-5 defeat at the Camp Nou, despite a seemmingly more defensive line-up.Despite selecting an almost unchanged side from the 5-0 win at home, Barcelona's attacking focus in Wednesday's Cup final defeat was very changed. In the win, most of their attacks came down the wings, whereas at the Mestalla most of their attacking play came through the centre.In the Cup final Real Madrid made a much higher proportion of their tackles in the defensive third than they did in the 0-5 rout at the Nou Camp, something that reflects Mourinho's intention of allowing Barcelona to come closer before trying to win the ball, refusing to be drawn out of position.(Green = Successful, Red = Unsuccessful) Despite making fewer crosses than Barcelona in their Cup final meeting, four of Real Madrid's balls into the box found a team-mate, compared to just one for the Blaugrana. This reflects not only the skill of the merengues' wingers, but also the lack of space available in their own area.In the Cup meeting, Cristiano Ronaldo was playing a much more central role up front, though this does not mean he was shirking his defensive responsibilities. The Portuguese made two touches in his own penalty area, as well as several other interventions near his own halfway line.

The images clearly show that Real Madrid have finally managed to get out of the their own half or at least managed to keep Barcelona out of theirs. However, the possession stats are unchanged.

The next two matches between the two will be tough ones. The tactics from both sides will be really thought out and it won’t be surprising if the Champions League matches will be as goal-less as the two already played.

Guardiola will probably be a bit worried over the depth of his squad, or lack thereof. Four very important, high-stress matches inside a month’s timespan will take a lot out of his preferred eleven and Barca do not have enough backup players to come out and perform.

Injury Updates

Barcelona: Eric Abidal has been out after being diagnosed with a liver tumor. Bojan Krkic is suffering from ligament damage and has been sidelined for the rest of the seasons.

Carles Puyol was stretchered off during the 1-1 draw in Madrid as a precaution. He was then on the bench in the Copa del Rey final and there is no definite news on his inclusion in the Champions League draws.

The latest concern for Guardiola is the injury of Adriano during the closing stages of King’s Cup final. He tore a muscle in his right thigh and is ruled out for four weeks.

Real Madrid: Their latest injury set-back is Sami Khedira. Mourinho said it will take a miracle for him to play in the semifinal. Angel di Maria and Emmanuel Adebayor are also doubtful.

Alvaro Arbeloa, however, is suspended.
