In football, when things aren't working, the first to be blamed is the manager. And if the situation doesn't improve, the fans start looking at the board. At Real Madrid, Florentino Pérez seems to have everything under control. Twenty-three years in the position, absolute power, and seven European Cups give him a certain degree of leeway. But in recent years, his tenure has had more lows than highs.

Álvaro Arbeloa's debut as Real Madrid coach ended in a resounding Copa del Rey failure. Los Blancos unexpectedly fell in Albacete (3-2) in the round of 16 after a very poor performance in both attack and defense, lacking ideas and physicality. The match was decided by a goal in the final minute of stoppage time. Jefté, who had come on in the second half, became the local hero on a night that the fans who packed the Carlos Belmonte stadium will not easily forget. In just four days, Los Blancos lost two titles: the Supercopa and the Copa del Rey.

When Barcelona fans think of Álvaro Arbeloa, Gerard Piqué probably comes to mind. During one of the most tense periods in football history between Barça and Real Madrid, the Barcelona defender mocked his Real Madrid counterpart, saying they weren't friends, simply... "acquaintances"He paused sarcastically after the "cone." This was Arbeloa's nickname, which Piqué, in a war of words at the end of 2015, blurted out during a press conference. A decade later, the now-retired footballer becomes the new Real Madrid coach, replacing Xabi Alonso.
