Real Madrid coach Carlo Ancelotti openly admitted that his side are in a period of poor form after Saturday's 1-0 loss at Athletic Bilbao.
Los Blancos were held to a 1-1 draw at home to Villarreal and their defeat at San Mames means that Barcelona can displace them at the top of La Liga with a win over Rayo Vallecano at Camp Nou on Sunday.
Gareth Bale went desperately close to cancelling out Aritz Aduriz's headed opener for Athletic when his long-range cross-cum-shot struck the post but, for the most part, Madrid struggled to break their Basque opponents down.
Indeed, Ancelotti was the first to admit that Madrid, who have scored 75 goals in La Liga this season but just one in their last two games, are not at the top of their game right now.
"I think we pushed hard in the second half and we were attacking all the time," the Blancos boss told reporters.
"The team has a problem in that we need to have a clearer idea of what we're doing in attack.
"We don't circulate the ball fast enough and the strikers are not getting any chances.
"It's weird to say that Real Madrid have troubles in attack because we have scored many goals but it's true.
"My team is playing poorly and I have to take all the responsibility.
"But I will not give up because the league is complicated and it is not finished. We will work hard to turn things around."
Madrid next face Schalke in the Champions League on Tuesday before resuming their Liga title challenge at home to Levante on Sunday.
