Barcelona and Real Madrid are among the most successful sports clubs in history.
The two La Liga rivals meet on Wednesday in what promises to be an epic two-game series in the Champions League semi-final.
Both clubs are very familiar with the other, so the match promises to have plenty of intensity.
