How can you judge Pogba to have qualities that can be compared to Messi, Neymar and Mbappe? While in reality, Pogba only shone only when Pogba played at Juventus in the past before Pogba returned to Manchester United. By only having short good results at that time, then I don't think Pogba at all has the same quality as other greater players as you mentioned. Because for me, Pogba was not too fancy and maybe only the media made his career popular at that time and in fact, playing at Manchester United also Pogba did not have good results at that time either.
I also don't agree that Pogba has the same qualities as Messi, Neymar and Mbappe. But it must also be admitted that he is a player who has extraordinary talent, but since winning the World Cup he has started to change his attitude. He demanded a huge salary and in the end he left for free and injuries can't lie because in the last two years his performances have been very bad. Maybe this is Pogmentary's karma so that Pogba's career is starting to decline drastically.
What I remember when Pogba was still in United's uniform was when he was injured and asked to do his own recovery outside the club but instead he went for a walk with his wife and then someone took a photo of him and sent it to the MOU, finally Boom the relationship between the two broke, and when he was already there Juve also happened to be injured, he did the same thing by wanting to recover outside the club. And the peak is now that he is positive for doping, I would imagine his football career will be over.
Messi, Mbappe, Ronaldo and Neymar are attackers, while Pogba is a midfielder. Pogba probably deserves to be compared to De Bruyne, Ilkay Gundogan, Bernardo Silva, Bruno Fernandes, Christian Eriksen and most other midfielders. In my opinion, that makes more sense than comparing Pogba's quality with a series of top strikers.
Currently, Pogba's career looks like it will soon fade after he was accused of using doping. The results are positive and of course this will have a big impact on his future at Juventus. I'm not sure if Pogba can still play at a high level due to his recurring injuries, but Juventus will probably drop him as soon as possible considering Pogba can't contribute much.
