Daniel Sturridge is due to return to the side in September.
Sturridge has been sidelined since April after having surgery on his hip, and has been in Boston as part of his rehabilitation, with reports from the Guardian suggesting he should return to Melwood very soon and could be available for the trip to Old Trafford after the international break.
He said: "I do think that when Daniel Sturridge comes back – and what a boost it is to have him close to fitness again – we could line up with a midfield diamond and two up front with Sturridge joining Christian Benteke.
"That would better suit the players we have.
"There's not quite the right balance at the moment, and there's certainly a tendency forJordan Henderson and James Milner to do the same job."
It was certainly a system that Liverpool tried during the pre-season matches but they have started with something resembling a 4-3-3, and Molby thinks there has been too much of a muddle to the midfield but the energy has compensated for it.
Christian Benteke playing alongside Sturridge has the hallmarks of a formidable partnership, with both forwards capable of scoring 20 league goals and can offer a different variety to the side's play.
But the Reds also have the option of a playing a rotating front three with the pair, along with Roberto Firmino when he has managed to get up to full fitness following his move from Hoffenheim this summer. It was a system that was pretty effective during the 2013/14 season at one time, but Liverpool still have their options.
With the striking options in Danny Ings and Divock Origi who have yet to make their full debuts, it will be interesting to see if this system is adopted in the Europa League when that gets going in September.
It could be a while before Sturridge is getting regular game time even when he returns to the first team so it could be until the midway point of the season before we see any noticeable change to the Reds way of playing in order to accommodate the forward.
