If people constantly persist in comparing Pogba to midfielders who have got next to nothing to do with what he does, he is going to 'lose' every single time. Essentially, people are creating strawmen and then knocking them down and saying 'told you so' as if they've offered any objectivity at all.
Modric, Verratti, Koké and so on are not players that should be compared to Pogba, and the fact people either wilfully ignore that or don't ackowledge that highlights why this thread is all over the place and just looks like a free for all to pan Pogba for not being the same type of midfielder as the aforementioned. Pogba would play alongside, or most likely, further up the field with all of these players, not instead of them, and only Koké would have a prayer of affecting a game high up the pitch in anything like the manner Pogba is expected to do.
To further illustrate the point, Pogba has more goals in the 2015/2016 domestic season than the 3 players mentioned above, combined, that either makes them deficient in a key aspect, or, it means they do a different job on a football pitch to what Pogba is expected to do.
If you compare players to type, you get to see what they are, or are not, made of. Otherwise, you're just picking favourites in a skewed environment; pit Pogba against the correct type of midfielder and a fair assessment can be made.
He's not the best midfielder of his type, not by a distance, imo, as he has some way to go to round out his flaws and improve his consistency, but he is being written off so readily, you'd swear he was some run-of-the-mill player, which he clearly is not.
