I don't disagree with any of that, but my argument is sevenfold.
I don't see KD starting over Cantwell as a #10. Hagi may even be ahead.
He doesn’t actually score many goals; 5 is about average. I think Cantwell gets us more, Hagi gets more, and even Raskin played further forward might get us more.
He doesn’t look the most mobile for the #8 spot, although that may be down to a lack of fitness.
His pressing didn't look great either - again, maybe settling-in issues.
I would prefer Raskin further forward, as an #8. He's good as the #6, but I think we'd see more of his energy and goalscoring if he's played further forward.
If we continue with the diamond KD's defensive issues may be masked as he will have cover and won't get isolated.
Arguably our best DM in recent seasons has been Davis, not great defensively. Do we even need a pure DM in most matches anyway?
It won't happen: Beale is too stubborn to take my advice; he doesn't repond to any of my numerous, numerous letters...
