Murphy said: "I think with El Hadji Diouf playing well on the right it's helped the manager have different options and we have players who can rotate around different parts of the field during a game. It's very flexible and makes us less predictable.
"I don't mind playing on the right, but in the middle you've got the chance to grab the game by the scruff of the neck a bit more.
"I think it's helped me being in there alongside Stevie [Gerrard] because we link up well. Neither of us sit in front of the back four, but we have a good understanding where one of us bombs forward sometimes and the other sits or vice versa."
