For the third time in 12 days, rivals Real Madrid and Barcelona take to the pitch to add to their storied history. Only this time it's under the biggest set of circumstances yet.

The Spanish powers meet at Estadio Santiago Bernabeu in the first leg of their UEFA Champions League semifinal tie (2:45, FX/FoxSoccer.tv/Fox Deportes) with the stakes rising high after their tense bout in the Copa del Rey final last week.

Both coaches are getting caught up in the heat of the moment as well, as Pep Guardiola and Jose Mourinho exchanged jabs at their pre-match press conferences during the week. Both will have to overcome some personnel losses, as Barcelona will be without Andres Iniesta and Maxwell, and Madrid will not have Ricardo Carvalho or Sami Khedira available.
