A Real Madrid forward line without Benzema is a forward line that hardly scores. I guess that's why Zidane always plays him.
Unfortunately, it is true.
However, by playing Benzema in all the matches and with full time, it increases the chance for him to get injured. Zidane has no choices, Benzema must play at all the remaining matches to score, but it will be wiser if he doesn't play full-time (
90+ minutes). Why not let another striker play as the starter? Then Benzema can substitute him if it seems hard to score in that match.
I also see that Real Madrid is very dependent on Benzema, even though he is no longer young and playing full time too often puts Benzema
at risk of injury. I understand there are not many pure attackers at Real Madrid, therefore Zidane relies too much on Benzema up front
to score goals. I think Real Madrid must have to get a new striker next season, to be able to replace Benzema. Of course don't buy young
players, but buying star players who have quality that is not different from Benzema, So it makes it easier for Zidane to rotate players,
especially on the front line.
