Real Madrid president Florentino Perez called club legend Michel a 'fraud' for his part in Juan Mata leaving the club.
Spanish publication El Confidencial have leaked the audio of conversations Perez has had during his tenure with 'Los Blancos'.
The latest leak has Perez going in on Michel, who spent 14 years at the Santiago Bernabeu.
He was Real Madrid B manager for a year in the mid-2000's and has been accused of forcing Mata out.
Perez vented per the Mirror: "I think Michel is the one who made the hole for Mata [to leave], he is the one who threw him out of Real Madrid Castilla to put his son in the team.
"He is a fraud!"
A tape from three years prior also sees Perez unload on Michel by claiming: "He is a very bad coach, a guy who has done nothing. He is not a coach."
Mata left Madrid and signed for Valencia, establishing himself as a Spain international and being part of their World Cup winning squad in 2010.
He signed for Chelsea in 2011 and helped the club win their first Champions League title a year later, while also winning Euro 2012 with Spain.
A Europa League triumph followed in 2013 before joining Manchester United as their then-record signing in 2014.
Seven years at Old Trafford has seen Mata win the FA Cup, Carabao Cup and Europa League.
The 74-year-old went on the offensive with Cristiano Ronaldo and even called the five-time Ballon d'Or winner a 'sick man.'
"He's crazy," Perez was quoted saying about Ronaldo.
"This guy is an idiot, a sick man. You think this guy is normal, but he's not normal, otherwise, he wouldn't do all the things he does."
Perez hit back with a statement which read: "Given the news broadcast in El Confidencial, in which phrases attributed to me are reported, I think it is necessary to clarify.
"The reproduced phrases are pronounced in conversations clandestinely recorded by Mr. Jose Antonio Abellan, who has been trying to sell them for many years without success.
"It is surprising now that, despite the time that has elapsed, the newspaper El Confidencial reports them today.
"They are single phrases of conversations taken from the broad context in which they occur.
"For them to be reproduced now, after so many years have passed since those conversations took place, is I understand due to my participation as one of the promoters of the Super League.
"I have put the matter in the hands of my lawyers who are studying the possible actions to take."
