Last Wednesday’s Copa del Rey semi final clash at the Santiago Bernabéu saw Real Madrid receive three yellow cards for a total of 19 fouls committed. On the other hand, Barcelona was shown the same amount of cards for just five fouls committed. Barcelona averages a card for every 6.15 fouls committed to Real Madrid’s 5.27. Espanyol is the worst with a card for every 3.86 fouls committed.
