Sorry, I didn't get you there.
But I'll clarify what I want anyway.
I don't particularly care whether we get the playmaking from deep or from the third/advanced CM slot - don't think it makes a huge difference.
Last season we had Gerrard as the playmaker at the base, with Henderson and Allen being the two advanced utility CMs. This season we seem to have Lucas and Henderson as sitting CMs, with Coutinho offering playmaking as the third/advanced CM.
The point is to have at least one of your midfield three capable of getting on the ball and offering some guile.
Given that most of our midfield personnel (Allen, Can, Henderson, Lucas) are better in the two deeper CM slots (and don't offer much playmaking themselves), I think it's really the third/advanced CM slot we need to look at to fit in our playmaker.
My point was that Allen was probably originally bought for this role. He's clearly not cut out for it. Coutinho has played this position now with some excellent success, but if he's injured, I think our midfield could start looking flat. I certainly don't mind then looking at players like Pjanic - who play in that third/advanced CM position.
Of course you could take the view that Lallana can fill in if Coutinho is injured, but I wonder if a midfield of Lucas/Can, Henderson and Lallana offers much guile - unless of course your attacking trio is so good that it just needs a hardworking midfield behind it.
