Real Madrid keeper Casillas baulks at reigniting Busquets feud
Casillas rapped his Spain teammate for his stamp on Real defender Pepe during the El Clasico.
Ahead of tonight's Copa del Rey final, Casillas said: "I already spoke about that the other day. I'm not going to get into it again.
"If I said something the other day, I don't care if someone has responded. I'm not going to add fuel to the fire and create more debate."
