Ruggeri: They set fire to my house with my parents inside when I left Boca for River Copa Libertadores Previewed this weekend's match

Former Argentine player Oscar Ruggeri is a man very familiar with the Superclasico, having played for both sides, and he has revealed the unfortunate lengths some fans go to as a result of the rivalry.

In addition, Ruggeri also starred for Real Madrid during his career and all three of those clubs will be connected this Sunday.

That is because the second leg of the Copa Libertadores final takes place at the Estadio Santiago Bernabeu and he looked ahead to the clash with Onda Cero's 'El Transistor' programme.

"I played for both River and Boca and I had a great time with both teams, but when I went from Boca to River they set fire to my house with my parents inside," he revealed.

"When they burned my house, I went to see the head of the Barras Bravas of Boca because he controlled everything and I told him it was the last thing I was going to put up with.

"Those guys ask you for things when you are a player and you are afraid because they threaten to do something to your family.

"This game will be interesting.

"River are maybe playing better, but Boca are more effective and can score out of nothing."

Ruggeri also had nothing but praise for two of the key figures at his former club Real Madrid, who he believes have a star on their hands if they secure the signing of Exequiel Palacios of River.

"Florentino Perez is a legend and, if I'd had him as president, I would have stayed there for a couple more years," he added.

"Real Madrid also have the best defender in Sergio Ramos.

"In terms of Palacios, he is the best player that they have in Argentina today and has a lot of class and personality.

"If Real Madrid were to buy him then I'd love that because Real are the best in the world and he is a massive talent."
