If someone says Real Madrid defense is weak, then what is the most losing goals ever conceded to Real Madrid, Real Madrid have Courtois the greatest goalkeeper and even though they escape the Real Madrid defense but will not have a chance to score a goal from goalkeeper Courtois.
Nobody said Courtois was bad because it was very clear that in terms of goalkeeping at Real Madrid, Courtois deserved a lot of appreciation because his saves were extraordinary, but it would be very complete if Real Madrid's defensive line became stronger again. So a goalkeeper like Courtois won't be too tired in saving a ball shot at goal directly.
