Porto goalkeeper Iker Casillas has urged Real Madrid management not to panic.

Real coach Julen Lopetegui is fighting for his job after Saturday's dismal defeat to Levante.

Asked about his old club's situation, Casillas reasoned: "Keep calm, the season has just started, the white fans are demanding but also understanding, there has been important changes in the past months."

Casillas also confirmed reports he's informed Spain coach Luis Enrique that he's available.

"Of course I am! I understand that Luis Enrique has his ideas for this new stage but I have my dream of returning."
