I'd say it was more fluid than the standard 4-2-3-1.
We seemed to start off with a pure diamond and with two up front but then asked Kone to cover their full back going forward.
I think it turned into the sort of "melted" (Rodgers would love this) 4-3-3 that we saw away at Newcastle in 13/14 where basically Cleverley was asked to cover a lot of ground to allow Lukaku, Kone and Barkley to sort out between them who could stay higher up the pitch for counter attacks/cover their full backs.
Cleverley ended up on the right for much of the 2nd half for example.
So did we invent the False 7?
