You compared him to a young Scholes though, and they're really nothing alike. Young Scholes was lethal in the box, prolific, and a threat at all times in the final 3rd. That's not Verrati.
Scholes moved further back over his career because of age and necessity, and the Scholes in the last stage of his career is the most comparable to the little Italian, as he pulled the strings all game whilst rarely shooting or getting into the final third. In terms of latter-day Scholes, your comparison is pretty fair.
I just don't know about this. Yaya started out as a very good DM and deep CM who made his mark long before he got to the PL, and got lazier and lazier as well as more unfit throughout his career. He's a footballer who just doesn't look arsed rather than inept and unsure of what he is supposed to be doing on the pitch. In certain defensive situations, Pogba is just clueless and doesn't know where he's supposed to be - he doesn't have the same foundations as Yaya as he's always been an advanced CM or a deeper AM.
Gerrard was all-action with great ability but little footballing intelligence or refinery in his game, which is why he looked a lesser player in slower games or when his bluster wasn't working. Gerrard gave everything he had for 90 minutes and wasted a lot of energy in the process. I feel like his moments of spectacular play were in combination with him wasting his massive energy reserves by trying to be Roy of the Rovers. Gerrard also never let a game pass him by, and would go off ball-hunting and losing himself positionally in desperation to affect the game. Probably Pogba's biggest failing is the apathy he has and willingness to wait for the game to come back to him rather than get involved at all times ala Gerrard.
I get what you mean about Yaya at his best at City, but Pogba's scope and skillset is vaster than Yaya's ever was - the guy is a sublime crosser of the ball and his passing as a whole is superior. Yaya at his best for City was a drive through the middle like a tank kind of player, I think Pogba will always be more subtle, deft and elusive than that, but ultimately it's productivity that is the yardstick and I think in the right set up, Pogba probably can't match someone like Yaya's best assist+goal numbers, but can get close whilst being even more of a thorn in the side for opposing sides, albeit with a different approach.
For me, Pogba's measure should be matching the productivity of Oezil and Fabregas at their best. He's got little excuse to not provide as much as they do, or did, in Fabregas' case.
