Well I do of course base it by the things that we the public can see. Pogba dismissed the opportunity to play and listen to one of the greatest managers of all time, and to do that and take a step in a completely new direction, you have to listen a lot to someone who assures you and tells you that you can succeed and be better off elsewhere (And Raiola was right - short term at least). So he moved, and therefore we can assume that he definitely listens to his agent a lot. It wasn't even like Pogba had patience with us. He moved at age 18 and Raiola was advocating all the time by then. Of course we can't say for certain that he depends on others like his agent to get through his life, and that wasn't what I meant.
I'm just saying Pogba clearly is influenced by him, and has been from a very young age. If someone gets it right the first time, you're even more likely to listen to him the next time - and that time happens to be where Raiola apparently
makes 41m in agent-fees for a move that hasn't even been good for Pogba's career. But oh wait, don't worry, he'll just make it all good again by helping him to Real, PSG or Juve... of course for a massive agent fee, and now Pogba will surely be happy again. How unfortunate that Raiola made about 60m in the meantime.
