The speech came several hours before Florentino Pérez launched his own counter-campaign with an aggressive speech that linked Riquelme's candidacy to the Ramón Calderón era.
The challenger's event was structured around a flagship proposal he called the "Ciudad del Socio" — a planned facility that he described as the largest membership-focused initiative in the club's 120-year history, designed to give socios a dedicated space they can access without requiring permission from the club hierarchy.
"There should be a place where they don't have to ask permission from anyone," Riquelme said.
He used the presentation to catalogue what he characterised as a systematic disconnection between Real Madrid's institutional governance and its ordinary members — a theme he returned to repeatedly across the morning.
On ticket access, he was direct.
"I don't know anyone without significant contacts who has been able to buy tickets as a non-season-ticket member. But then the resale market is full and people are paying three times the face value."
He attacked the governance of the VIP box allocations.
"There are many people involved with conflicts of interest, to put it that way. We need transparency in management."
He noted that historic fan associations — peñas that had been promised visits to the Valdebebas training complex as a special recognition — had waited seven years without receiving a response to that invitation.
"This is a place where they should not have to ask permission from anyone."
The most pointed institutional attack came on the question of what he described as preferential access for individuals close to the current administration: "There are people who can become a member, a season-ticket holder, a match-ticket holder and a compromisario in record time. That is extraordinary. Congratulations to him. But the rest cannot."
He also raised the issue of the Santiago Bernabéu's renovation, challenging whether the €1.7 billion redevelopment would generate the commercial revenue that had been forecast.
"We can build a facility that can be profitable and generate the revenues that, today, after an investment of 1,700 million euros, we are not going to be able to generate."
Riquelme called for a public debate between the two candidates before the 7 June vote — a request Pérez's camp has not yet responded to.
The election is the first contested Real Madrid presidential ballot since 2006, when Calderón defeated Pérez and ended his first term. It takes place on 7 June.
