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.
The fate of the two clubs Barcelona and Madrid this season is almost the same, at least Madrid did not do a lot of big enough aggression like last season but is now able to be in second position. Barcelona is still not safe enough at the moment. As for Ancelotti, whoever coaches Real Madrid, the players will still have the quality and mentality to win. For now, Benzema has been unproductive after picking up an injury, and Ancelotti broke Vinicius to continue to fill the void. Maybe next game Benzema can get back to his best. Or indeed they are after the Champions League first, then play optimally in La Liga.
It is important to note that the problem exists for both teams. As far as the attacking and defending sides are concerned, both of them are not doing very well at all. To be honest, I think that Real Madrid's defense looks pretty terrible. This season, they have not been able to perform well defensively. As far as I know, they have only kept one clean sheet so far this season. The reason why Barcelona has a more favorable goal difference than Real Madrid is because of this factor.
There is no doubt that Barcelona is not a safe place. It will be decided in the next match who will be the actual leader of La Liga. As well, I do not understand why people are expecting so much from Karim Benzema. He is a 34 year old man and it is easy for him to sustain an injury at this age. But Barcelona also does not look very encouraging at this moment. Right now, the attack is not well coordinated with Barcelona.
