Spain coach Vicente del Bosque has defended Real Madrid captain Iker Casillas.

The veteran goalkeeper conceded four goals in their Champions League defeat to Schalke on Tuesday.

"He didn't play well and he himself admitted that," Del Bosque told Marca.

"However, he saved Madrid at the end."

He added: "We're not going to make any changes unless it's for something worrying. I think he's in good form."
