Only goalkeeper Jose Reina and versatile defender Alvaro Arbeloa have played in all of the previous five games.
Benitez said: "The squad is stronger now than last season, you can see the quality of the players and the different things they can bring to the side.
"We are thinking about the whole season, if you have problems in one game you know you can change the situation.
"It is something that maybe we did not have before, it means we are more able to take control of a game.
"Our idea has been to improve in every position, to have two players in each position playing well. That means I do not need to talk about one or two players as the most important ones in the team.
"I have different players in each position and now all of them can play well."
Benitez believes that the uncertainty is making everyone play better.
He said: "Against Toulouse the two strikers, Kuyt and Crouch, knew that there was Torres on the bench waiting while Voronin was sitting in the stands, also waiting.
"I feel that with that situation now, if we create chances we will score more goals because everyone will want to make an impression."
