Jorge Perez has announced he will run for president of the Spanish Football Federation (RFEF) and challenge his former boss Angel Maria Villar.
Villar has been at the helm of the Spanish FA since 1988 and has already confirmed he will run for an eighth successive term after failing in his bid to become UEFA president in September.
Perez, who was dismissed by Villar as RFEF secretary general on Oct. 11, told Cadena Ser radio: "Today I announce my candidacy for president of the Spanish Football Federation [RFEF].
"I believe Villar can be beaten although it will be difficult."
Perez, a journalist by profession, believes he is the right candidate for the post.
"People who work in football know me and that is a good thing," the 60-year-old said. "They know who I am, how I work and serve football. My motto has always been to be humble and to be of service. "I think times have changed and we must move on. A change is needed.
"Villar may have done good things over the years but now we need to work a different way. We need elections. I hope the election will be called as soon as possible, later this month."
Elections were initially scheduled for earlier in the year, but Villar delayed the elections in order to run for UEFA chief and his move was heavily criticised by La Liga president Javier Tebas and Spain's secretary of sport Miguel Cardenal.
The 66-year-old would go on to withdraw his candidacy to replace Michel Platini at UEFA after failing to get enough support.
"Two years ago my relationship with Villar ended," Perez said. "When I announced my intention to become president of the RFEF, the president stopped talking to me. I last spoke to Villar in December or January."
Despite their poor relationship, Perez was stunned to be sacked by the RFEF for disciplinary reasons last month.
"I didn't expect it," he said. "And more so to be sacked for disciplinary reasons.
"They told me the reasons for it were because I had spoken to several radio stations and given interviews to several newspapers.
"I feel badly treated by the RFEF in the last few months. They have done things I wouldn't wish on anyone and there was no need for that.
"The matter is now in the hands of my lawyer and I will defend my rights on the courts. I have worked 26 for the Federation and I believe this is an unfair dismissal."
