Former Brazil striker Ronaldo has spoken of his positive relationship with the presidents of his playing career.

Ronaldo is now a president himself as owner of Real Valladolid.

“The best, a school of the highest level. I start from the last one, Andres Sanchez of Corinthians, today a great friend of mine, he revolutionised the club," he told La Gazzetta dello Sport.

“And I go back to one of the first, José Luis Nuñez at Barcelona, with whom I didn't get on well, I was only there for one year and it served to make me understand how not to do things.

“I had signed the renewal and after five days he changed his mind and tore it up, that's why I came to Inter.

“Where I found Massimo Moratti. I had an incredible, incredible human relationship with him. He was one of the most important people in my life. How he treated us, how he spoke to us, how he cared for us.

“I also had a very good time with Florentino Perez, he started the modern era of football, with the 'Galacticos' and the development of the commercial area, which until then had never been exploited. He started monetising the image of the players."
