Fernando Torres, Andriy Voronin, Peter Crouch and Dirk Kuyt cost £36million between them, and if you add wingers Jermaine Pennant and Ryan Babel to the equation, that is £54million of attacking talent scrapping for places at Anfield.
Benitez's rotation policy, so maligned in the previous couple of years, is creating the different between this campaign and last, claims the Spaniard.
He said: "There is a long way to go, what is more important is to make sure the team maintain the same mentality.
"The understanding between Torres and Kuyt is fine, but then when it was Kuyt and Voronin that was good also. It is the same when Crouch is playing with Torres, Voronin or Kuyt, I am pleased with all the combinations.
"All of them know what we want, their movement is good and I am sure it will improve even more over the coming weeks.
"Now we have four players with quality and different skills. I can now manage in a different way because you know all of them can score goals.
"You cannot say that Torres will score more goals that Kuyt, Voronin or Crouch. They can all score and they are all equal."
Benitez has sent the bulk of his squad off on international duty this week - 15 players in all - with Liverpool at their highest point since he took over three years ago.
He said: "I am pleased now because the team are scoring, we are not losing or conceding goals and that is all very positive for us.
"We are different from last season. We are able to finish teams off, we can score the first and then the second, and the game is over. It is different to some of the games last season.
"I am sure the fans will enjoy where we are. But for me that is not important now, it is too early. We must keep going and see what happens in a couple of months' time.
"The work rate of the team is so good, Kuyt did not score against Derby but his effort and running was fantastic. Torres, Voronin too, I was really pleased with them all.
"We have tried to find wingers for three years, but now we seem to have a couple in Pennant and Babel. They can both work well out wide."
He added: "Jermaine has a better mentality now. He can play down both wings, he has more determination to attack defenders. Babel has pace and ability, we are better now in the wide areas than last season."
