In the summer of 1998, and chaired by Lorenzo Sanz, the Santiago Bernabéu adopted an all-seating arrangement, bringing its capacity down to 75,328 spectators.
When Florentino Pérez became the president of Real Madrid, he launched a “master plan” with one goal: to improve the comfort of the Santiago Bernabéu and the quality of its facilities, and maximise revenue for the stadium.
Pérez invested €127 million in five years (2001–2006) by adding an expansion to the east side of the stadium, as well adding a new façade on Father Damien street, new costumes, new boxes and VIP areas, a new stage in honour of the east side, a new press area (also located on the east side), a new audio system, new bars, integration of heating in the stands, panoramic lifts, new restaurants, escalators in the tower access, and implementation of the multipurpose building in Father Damien street.
Following the enlargement of the lateral east side and the creation of new galleries, the capacity of the Santiago Bernabéu was 80,354, all seated. The last change was an increase of about five thousand to a capacity of 85,454, effected in 2012.
In its history, Estadio Santiago Bernabéu has hosted four European Cup and Champions League finals. The first final was in 1957 between Real Madrid and Fiorentina (2-0), the second in 1969 between AC Milan and Ajax (4-1), the third in 1980 between Nottingham Forest and Hamburg (1-0), and the last one in 2010 between Internazionale and Bayern Munich (2-0).
Real Madrid presented plans to further upgrade the stadium with commercial and corporate facilities, and to increase capacity to over 90,000 seats. This was going to be done by renovating the stand facing the Paseo de la Castellana avenue, but it was challenged by the local council and blocked by the Tribunal Superior de Justicia de Madrid.
Finally in October 2016, Real Madrid and Madrid City Council have reached an agreement over the €400 million renovation of the Santiago Bernabeu — with the club accepting a court decision and modifying the construction plans now set to begin in 2017. The revamped venue, which will also carry a new facade, is expected to be fully completed by 2020.
