True, Real Madrid have a stable defense even that is confirmed by the appearance of their excellent goalkeeper, Courtois. Maybe some people think that Real Madrid's defense is weak because they saw Courtois being the last stronghold that was difficult to penetrate, so Real Madrid's defense didn't seem so dominant.
Thanks to Courtois, Real Madrid defense became solid because it was difficult to shoot on goal. We have seen Courtois' outstanding performance in the final match against Liverpool. Although there are many opinions that Real Madrid's defense is weak, it cannot be denied because it is more dominant that there is no strong defender to snatch the ball from the opposing striker.
