The Frenchman scored the lone goal for his side during Real's 1-1 draw against local rivals Atletico Madrid last weekend, but that didn't stop Benitez from withdrawing him in the 76th minute to introduce Mateo Kovacic.
Benzema told AS: "It's true I'm fed up of being taken off. I'm calm and will continue to work so I'm not always substituted.

"He took me off to get a result, for defensive reasons. It's true that the electronic board always shows the no.9. Ask Benitez why that is."
As a result of the revelation, Arsenal are now reportedly on red alert and would appear ready to make another move for the 27-year-old marksman.
All summer long there were strong rumours indicating that Benzema was unhappy in Madrid, with the general consensus being that he was unhappy with team-mate Cristiano Ronaldo stealing the spotlight and, potentially, his role as the lone striker.
Days before the transfer market closed, however, Gunners fans were left disappointed when Benzema confirmed in an interview himself that he had no intentions of leaving Real.
Now that Benzema and Benitez are experiencing difficulties, though, it may open up a possibility for a move to finally be made.
Arsenal have long been in search of a world-class striker - a position many feel holds the team back from competing at the highest level against Europe's best.
However, Arsenal's convincing victory against Manchester United this past Sunday showed that they have the ability to tear apart those regarded as elite, and coupled with Benzema could provide the spark that they need to bring more silverware to north London and assert their dominance both in the Premier League and Champions League.
