Real Madrid's reaction to their defeat against Real Mallorca in October could not have been any better.
Following that game, the team began to defend much higher up the pitch, and with more intensity.
Every player; including strikers like Karim Benzema, played their part by tracking back and closing down the opposition.
The three matches following the bad result at Son Moix vindicated this new system, as Los Blancos won against Leganes, Galatasary and Eibar respectively, without conceding a single goal, and went on to keep seven clean sheets in 12 games.
Belgian goalkeeper Thibaut Courtois has been one of the key faces in the Real Madrid defensive revival, but not the only one.
Players like Raphael Varane or Dani Carvajal have also put in exceptional performances in recent weeks, and as always Casemiro has been a commanding figure in the middle of the park.
Even a setback like Marcelo's injury has allowed Zinedine Zidane to experiment with youth and give promising youngster Ferland Mendy a chance to step up to the plate.
The Real Madrid coach will be hoping that the defensive solidity continues heading into the New Year, as both LaLiga Santander and Champions League are shaping up to be more competitive than ever.
