Could be Juve, but let's base it off the Pogba of last season, or the Pogba that was the only player outside of the top 2 to get in the team of the year.
Three of those 4 players would not be an improvement on Pogba, and the other one is perennially injured. None of them have the marketability he has either. Two of those 3 remaining players would cost at least £80m, the other is apparently available for £35m, though not a single reliable source has echoed this. If you're going to base this off value for money, then you're not making a very compelling argument.
I'm not going to do this for Verratti because of the different league and Neves had a bigger dip in form than I realised last season so fair enough on him but:
Tielemans (4 years younger)
Tielemans makes more successful tackles per game.
Pogba makes more clearences.
Tielemans makes more forward passes per game.
Pogba wins more aerial battles
Tielemans makes more crosses and through balls per game
Pogba creates more big chances
Tielemans is dispossed less
Pogba slightly edges successful pases
Tielemans slightly edges goals per game
Pogba slightly edges assists per game
Mount (6 years younger)
Successful tackles per game is pretty much even.
Pogba makes more clearences
Both make a similar amount of forward passes, possibly Pogba slightly edging it (I'm doing mental maths)
Pogba wins more aerial battles
Mount makes more crosses, Pogba makes more through balls per game
Mount makes more big chances
Mount is dispossed less
Mount makes more successful passes
Mount has a higher goals per game.
Assists they're pretty much equal per game.
I wasn't even going to bother doing Mount until after I did so I've not bodged this to make them look better. That's 2 CM's in the league, both quite considerably younger with room to improve (and in Tielemans case he's not exactly surrounded by exceptional talent) who pretty much hold their own against Pogba. I'd spit my drink out laughing if Chelsea or Everton put either on £350k+ a week.
I'm not going to go into other leagues where I've not seen enough of them, but inevitably there is the PL premium. If there is really no one out there for £80m and £200k per week who couldn't replicate or excede what we've seen from Pogba over the last 2 years, then football is in a sorry state.
