During the next three years, Pérez brought a lot of new faces to the team, including the German wonderkid Mesut Özil, and Ángel Di María, who both attracted attention from Europe's elite football clubs during the 2010 World Cup in South Africa. This squad enjoyed its share of domestic success in 2011 and 2012, with the club bringing home a Copa del Rey title and the Spanish League title. However, the club's lack of success in European competition and a disappointing 2012–13 season encouraged Mourinho to depart for his former club Chelsea.
