I'm not missing the point friend, I just have a different opinion to you.
Martinez, rightly or wrongly, doesn't want to expose both two young centre backs at the same time which is why I believe we have seen Galloway protected on one side by Naismith and generally seen more of a maverick winger on the other in Deulofeu or Kone (essentially a "wide striker").
If you believe that this is wrong, then fine. If you believe this is right however youd prefer one of the holding midfielders sacrificed for an attacking player like Barkley, or a crock like Gibson, then fine.
With respect, I think you're out of your mind. The last thing that team needs is more youngsters with more responsibility. The last thing that team needs is more attacking players shoe horning into it. Barkley playing deeper means more responsibility on him. I, others on here and Martinez don't think he's ready. Gibson playing there requires him off the treatment table.
I have no problem saying Barry requires a long term upgrade but we don't have one and again, with the injuries, further disrupting that side's fundamental partnerships is ridiculous.
The issue isn't Barry and McCarthy. It's Naismith and Lennon both playing. It's the inconsistency of Lukaku, Deulofeu. It's the suspension of Mirrallas. It's the lack of Pienaar. Its the lack of Pienaars replacement which Martinez very publically spoke about.
It isn't our only two holding midfielders.
If you believe differently, no worries. But I think you're spectacularly missing the real issue.
