He's not a Gerrard or Robson though. I don't just mean in terms of stature but also type of player.
IMO he has more in common with players like David Silva. He can do the bare minimum water carrying to play in midfield, but he's no Roy of the rovers and if the rest of the midfield isn't doing their job (and a bit of his) don't expect him to carry their burden.
Give him the ball with willing runners around him though, and he can make things happen, both in midfield and close to goal.
I am sure there is plenty to criticise about him as well, but I do think part of the problem is that everyone, Pogba probably included, is trying to make him a kind of player that he is not really suited to be.
He's nowhere near a Silva though. Silva has an appreciation of space and time that Pogba can only dream of. He has the physical traits of a Gerrard moreso than a Silva and he was groomed as that type of player when he was in the youth teams here.
When he left for Italy, he wasn't an obvious long-term fit for any of the two main midfield spots occupied by Pirlo, Marchisio, and later Vidal, and was instead the third man in midfield with license to bomb forward - again, not much different to Gerrard.
When he came back, he was meant to be the player we built around - a la Gerrard at Liverpool c.2004 but because he couldn't (or seemingly wouldn't) work in double pivot, that plan fell by the wayside and Jose went down the route of Sanchez. When Jose burned his bridges, Pogba was again given the keys to the team and was fantastic for two months playing in a Gerrard/Robson/Keane-lite role where he picked up the ball in deep positions, distributed it and bombed on. Again, the polar opposite to Silva and more like Gerrard.
He's not someone to build the team around and the fact that he still has these inconsistencies in application and effort at near enough the age of 27 reflects poorly on him as a player and a professional.
Zidane might have these dreams of getting Pogba to be the best player in Europe, but considering he's building his new project around two temperamental geniuses in Pogba and Hazard, who only turn up when they feel like it (and in the case of Hazard) can have whole seasons where they are phoning it in, makes me think his project is doomed to fail. Maybe he can fluke a CL or two, but in the age of VAR that's looking pretty unlikely as well.
