Pogba played with Vidal, Marchisio and Pirlo. Pjanic had to play with Khedira and Matuidi.
Buffon, Barzagli, Chiellini and Bonucci were also better and younger from 2012-2016 than they were from 2016-2020.
It amazes me how disrespected Pjanic is compared to Pogba. Pjanic achieved everything Pogba did for Juve, and did so while playing for Juve sides that were (on paper) not as strong.
On a team level - Yeah since the only difference is to win the CL which neither one had.
On a personal level - Pogba was surrounded by great midfielders in 2015 but what happened in 2016?
Vidal left and Pirlo (cant remember - Either retired or way below his prime)
Pogba got the responsibility of carrying the team through midfield and he sucked at first but then adapted amazingly. He definitely carried our midfield that year.
As for Khedira - 2016 and 2017 Khedira were about the same - His true fall started in 2018
Matuidi - He had a good first year actually but started really being a headless chicken later.
What I mean in the end - Pogba had a test of carrying our midfield in 2016 and he succeeded in a great way.
Pjanic got that responsibility and he lasted for almost a full year before showing he cant carry everything on himself.
Im not saying Pjanic wasnt a great player as he definitely has been a great player but if I isolate Pjanic and Pogba from the team and talk about what each one did in terms of tasks on the field - I can definitely say Pogba was much more impressive as he drove our team forward had the strength to hustle and had some nice presence in the air.
In fact Pogba was so amazing Man Utd didnt let go their will to sign him.
All this being said is not in order to disrespect Pjanic but to show just how good Pogba was and he was a monster!
