Benitez told The Sun: "I don't play Gerrard in the position he likes the most - but in the position where he brings ME the most. And in England, they have trouble understanding that.
"Steven is a very important player for us. And sometimes I have to readjust my whole line-up in relation to him."
Benitez is adamant Javier Mascherano is the main man in the middle of the park and said: "Gerrard brings something extra and real quality because he's a great player.
"But it's not with him that you're going to stabilise the team - he does not guarantee that style of play - his is more a certain spirit and a leadership.
"He has all these natural qualities. I won't win matches with Mascherano but I know that when I play him, I have less chance of losing.
"He has great tactical discipline and a great capacity for work which allows the whole team to be balanced."
