I think you both have good points, not sure what it is, but i really feel that perhaps moving Luis out to the left wing instead of playing him as a striker and maybe using Shelvey as a false 9 could improve our fortunes.
Shelvey looked outstanding the that role on 2 occassions now, and despite the fact he hasn't scored himself he has certainly influenced play in such a way that allows our other players to score goals, although he did get one in one of those games, i believe it was a close range header....
I think Brendan might have given himself a headache following our displays with such a setup...
