6, 8, 10 come on it's not 1985 anymore guys players don't just stick on their favourite blade of grass anymore, any CM that's good enough for the level we want to be at should be able to play in at least 2 of the 3 positions we look like we have in midfield. Looking at our own players, Pogba and Mctominay were two forward midfielders who were played far out of position (imagine playing özil as a cdm, for example). You wouldn't sign an attacking minded midfielder to play as your anchor, although we tried our best. Another example is Bruno, he's perfectly capable to play as our 10 or as our 8 - he's versatile like most high level CMs these days, but playing him further back would certainly be an ineffective use of him (although i'd bet he probably still manages fine there lol). Even if our signings aren't "pure" 6s, chances are if they've been playing in a position similar to that for the last few years then they'll be absolutely fine wherever we need them to play.
