If Vinicius or Benzema are injured for a long time, then maybe Real Madrid will lose their place in the points table.
True. Without Vinicius or Benzema, Real Madrid attacking line won't have the power. They may survive in the top table of La Liga, but they probably will be eliminated by stronger teams in UCL. This season, Real Madrid must admit that they rely on these two players as the most effective strikers. So, Ancellotti must keep them always in a good condition.
Real Madrid's gameplay, on the other hand, suggests that they have become completely dependent on Vinicius and Benzema.
The best formation of Real Madrid strikers: Vinicius - Benzema - Asensio.
I've watched most of the matches played by Real Madrid so far, this formation is the most effective one. They depend on these 3 players in the attacking line.
