Real Madrid coach Zinedine Zidane says there'll be no underestimating Osasuna.

Zidane says Real must be focused to see off the strugglers.

“We're looking good because we've had time to do our work and physically we feel fine. It's a very difficult place to go, they're a tough opponent, they always were during my time as a player. El Sadar has always been a difficult place for us to go and that's not going to change," he said.

“It's a case of top against bottom and I don't like that idea at all because Osasuna always play well, particularly at home. We know what to expect at El Sadar, but we're ready for it and feel good physically."
