Stats are more relevant than whatever narrative you've thought up in your head to suit your argument, even more so when the stats make it so overwhelmingly obvious as to what his role is.
Those articles go no way to proving he's a B2B midfielder, in fact the first article actually cites all of his defensive stats as to why he's bossing the midfield. Tackles/Interceptions/Duels/Clearances. His heat map which is used as an example isn't very hard to understand when he's playing vs a side like Villa and United have 65%+ of the ball of course the majority of his average position will be in their half.
The 2nd article has one comment which speculates he could fill the B2B role if he moved to Spurs and the 3rd aricle is even more hilarious since the only inclusion of B2B was him being asked who his heroes were and he said Gerrard/Zidane because they could play either role.
Let's look at how he compares offensively vs the obvious B2B CM's in the league:
Yaya Cesc Henderson Schneiderlin Ramsey
Goals 36 22 15 9 17
Assists 15 41 20 2 16
SPG 3.1 1.6 1.4 1.2 2.2
KeyP 1.4 2.8 1.8 0.9 1.6
Drib 1.8 1.1 0.5 0.6 1.3
He's miles behind all of them in almost every category offensively. The opposite appears when you looks at his defensive contributions where he beats every single one of them with tackles/interceptions/blocks/duels/clearances and actually leads the entire league in a number of those.
