Real Madrid goalkeeper Iker Casillas risks the wrath of coach Jose Mourinho after talking up Barcelona and Pep Guardiola.

Mourinho has insisted on a 'bunker mentality' when it comes to their great rivals, but Casillas has gone off script.

"I respect Barcelona and what Guardiola does, but what interests me is Real Madrid and trying to win all possible competitions," he told Sport.

"We will start the season in a good way, facing Valencia, a team that plays very well and that always makes things very difficult. The goal is to keep winning titles."
