Players have been converted from their “original”...Yet we have had good success in trying Dier & Sissoko in new roles (Bale in the middle anyone? Ditto Modrich....). Don't get me wrong, if I see us field a team of square pegs in round holes, I'll be weary as fuck about it, but if the gaffa believes player X can work in Y role then I'm intrigued to see how switch pans out.
Position for decades.
Add Danny Rose to your list and countless others.
I see Foyth as a potential upgrade on Dier in DM.
And if Poch sees it that way, & an opportunity arises, he will try him there.
Poch absolutely loves a versatile player.
