Florentino reveals having to diffuse row between Real Madrid stars Ronaldo, Casillas
Ronaldo was angry over comments made by Casillas' girlfriend Sara Carbonero, the TV journalist, earlier this season.
Perez told AS: "I helped to solve this misunderstanding.
"Cristiano misinterpreted the words of Sara Carbonero, but this misunderstanding lasted ten seconds. They now have a perfectly normal relationship and wanted to go together to the Christmas event so people could see that everything was normal."
