Real Madrid coach Zinedine Zidane admits Casemiro's injury is a blow.
The midfielder has suffered a broken leg injury.
“We won't play differently because our vision is the same," said Zidane.
"Obviously some things will change because whoever replaces him won't be the same player but our idea remains the same: to keep the ball and play in the opponent's half. The idea is the same regardless of who's on the pitch."
