Real Madrid assistant coach Aitor Karanka says Iker Casillas will not be in the squad for this weekend's La Liga clash with Real Zaragoza.
The Spain international recently resumed regular training after a lengthy spell on the sidelines following a thumb injury, but Karanka has warned against rushing him back to action too quickly.
"Iker was given the medical all-clear last week, but he is not ready to make his return just yet. He will not be in the squad," Karanka told reporters.
"He will get the green light to make his comeback as soon as he's 100 per cent again, just like any other player."
Karanka then went on to dismiss reports that Jose Mourinho has sent Paris Saint-Germain coach Carlo Ancelotti a video with information about how Real beat Barcelona earlier this season.
PSG will meet Barcelona in the quarter-finals of the Champions League.
"Mou sharing info about Barca with Ancelotti? That's just ridiculous ." he said.
"Madrid are on the right track and we have to keep up our current form. We're lucky that our players didn't pick up any injuries while away on international duty."
