Real Madrid captain Iker Casillas has shrugged off criticism of his early season form.
Casillas hasn't been at his best so far this term.
But he told Madrid's official website: "You take it (the criticism) with a sense of humour.
"You have to respect people's right to criticise. As long as it's constructive criticism, it's a positive thing. When you've been at the top and in a club like Real Madrid this long you know that in two or three matches things can change.
"I've been living many years with this. You have to keep going and try to turn those dissenting voices around."
