Hit and miss, honestly. A lot of players are OP (Phil Jones, Rojo, Lingard - all are pretty usable, even for a Top-6 club). Pogba, may have needed under-rating, but he is still a beast in FM. Whereas Rashford could have used a bigger boost, I think. Same with Henderson and Greenwood, I think. Our youth, however, have been given a pretty good boost, so that I'm happy with. I've hated how United youth were generally rated over the past couple of years.Think most big clubs have bit overpowered players. Most have been for United, might be bias as I play FM mostly in England and PL
But overall, yeah, Top-6 clubs have some OP players. But like the researchers were stating at the SI forums, a lot will get changed for the main release as some DB changes didn't make it to the beta.
