Aritz Aduriz’s header was enough for Athletic Bilbao to sink Real Madrid 1-0, leaving Barcelona the chance to go top of La Liga.
Isco insists that while Real Madrid are “a little bad” right now, Carlo Ancelotti’s men remain more than capable of reclaiming control of La Liga by winning at Barcelona in a fortnight.
After being held to a 1-1 draw at home to Villarreal last weekend, Los Blancos suffered a 1-0 loss at Athletic Bilbao on Saturday, meaning second-placed Barcelona can go top of the Primera Division by beating mid-table Rayo Vallecano at Camp Nou on Sunday.
Isco confessed after the game at San Mames that Madrid’s players are struggling to explain their sudden slump in form but the attacking midfielder remains adamant that they can quickly turn things around.
“We leave here with a negative feeling,” the Spain international told reporters. “We had an advantage in the league but now we have lost it after two games without a win.
“We lack freshness and that’s not normal for Real Madrid.
“The league is difficult but it is long and we’ll go to Camp Nou in a couple of weeks with all the enthusiasm in the world.
“The team is physically well, so that’s not an excuse.
“We have a great squad and we can win at Camp Nou in two weeks. It is a decisive match.
“The team is a little bad now but this happens from time to time.
“Teams go up and down and changing the situation depends on the players. Our duty is to go back to the way we were playing before.”
Madrid face Schalke in the Champions League and Levante in La Liga before travelling to Catalunya on March 22 for their crunch clash with Barca.
