The addition of Pogba and Ansu Fati could at least make AS Monaco consistent in Ligue 1, as well as increase their chances of going further in the Champions League. PSG dominance in Ligue 1 will not be shaken even if AS Monaco manages to sign both players, finishing in the second position in the standings seems more realistic for them next season. It's been a long time since I saw Pogba in action on the field, and I think Pogba is very lucky to get a leniency after filing an appeal in court.
I think that no matter how hard Monaco try, they simply cannot and will not be able to affect PSG's dominance in Ligue 1. The level of the teams is too different, and their approaches are also too different. Monaco have traditionally focused on developing and selling players to other clubs, while PSG are set on getting stronger and stronger every season. For Pogba, of course, this is a very big luck, initially, there were questions whether he could even return to playing at all, especially with a potential lifetime ban looming. And now he is coming back to a very good and strong team.
