Madrid might not be the city Matías Fernández was most familiar with in Spain, but he was definitely more familiar with Madrid as opposed to London. When he was still a player for Villarreal, he would go to Madrid at least three times in a single season to play away games at Real Madrid's Santiago Bernabéu Stadium, Atlético Madrid's Estadio Vicente Calderón Stadium, and Getafe's Estadio Coliseum Alfonso Pérez Stadium. It was possible that London would replace Madrid's position a season later because he had to go to London at least five times in a season.
Villarreal, or "The Yellow Submarine," was Real Madrid and Atlético Madrid's direct rival the past few seasons. Matías Fernández was used to hearing boos from the home fans every time they played an away game against those two aforementioned teams. However, ever since he came to England, he realized that the boos from the Spanish fans amounted to nothing. The craziest fans in the world were definitely from England.
