Ancelotti must see this fact as a problem that must be resolved immediately considering Real Madrid will soon play in El Clasico. Barcelona as one of the most prolific teams in La Liga could embarrass Real Madrid if their attackers can't score more than one goal in every game.
Real Madrid must not rely too much on Benzema when scoring goals, they must take the slightest opportunity without having to pass the ball to Benzema feet. El Clasico match is very important for Real Madrid to regain control of the first position in the standings, because currently Real Madrid and Barcelona have the same number of points in the standings list.
Their record is the same, one series of seven wins. But this week they are busy preparing for UCL. Barcelona are struggling in their UCL lost two times in three match. I think right now Barcelona's focus is on the UCL. They try to take three points in every match. As for Real Madrid, they are better at UCL. Madrid's chances of qualifying are very open. I think the El clasico issue they'll think about after UCL later. I don't know yet if Benzema will play at El Clasicco later, but I'm hear if De jong and Kounde ready to go against Madrid.
Madrid already had a easier time during the UCL though, they matched up with easier teams and easier wins were the results, Barcelona faced with Bayern and Inter, which everyone expected them to lose to bayern, that much was sure, but Inter game was the only game people assumed they would win and they still lost, that's about it.
I personally believe that they are going to get a better run at things this time around, but I feel like they may still lose and shift their focus on la liga title as well. That's not a small achievement, if they win the la liga title that's a lot of money, and next year it would be easier opponents to play during the group stages as well.
