Adam Lallana
Adam Lallana was a mainstay of the front three for the Reds last term, but has dropped back to feature regularly in a midfield three this season.
The 28-year-old's success in the middle of the park has led to him matching his best-ever Premier League goal haul by January.
And, according to Molby, Lallana is now the key man in the engine room for Klopp.
"Of all the midfield players we have, Adam Lallana is definitely different. He has, without any shadow of a doubt, turned out to be the key midfield player.
"What Adam Lallana is, and maybe some people won’t see this, is he’s a playmaker. He’s not a playmaker who sits back and dictates play; he’s a bit like Iniesta, he’s that 15 yards further forward where he dictates the direction and the tempo of the play.
"He’s been very impressive, he’s been very, very important – so important that I make him our key player. Lallana is very good at manipulating the ball, creating space for himself. There’s nothing like time and space – if you don’t have time and space, it’s very, very difficult to play, but you’ve got to be able to create it. He creates it and never did enough with it, but I think the manager has said, ‘when you do this and when you do that, this is what I want you to do’.
"Now, when Adam Lallana is on the ball and he manipulates himself into a situation where he can do something, you’re almost on the edge of your seat, you think something is going to happen."
