Real Madrid defender Raul Albiol says they must not take Real Zaragoza lightly.
Madrid go into the match 19 places and 24 points above rock-bottom Zaragoza, who have picked up just one win in their opening 14 matches this season.
Despite that though, Spain international Albiol is remaining cautious, saying: "It will be difficult and dangerous because they are fighting to get out of the relegation zone.
"They are going to give it everything to pick up points in front of their fans, like we saw last season."
Madrid needed an 82nd-minute winner from Kaka to claim a 2-1 win at La Romareda in April.
"They are going to be very focused and we cannot give them any reason to gain in confidence."
