I have bought it last year and i don't think it's worthy since it will only give you PA/CA and a "future" perspective.
Knowing what players have what can ruin the fun, so be careful.
My fault last year was to buy all players above 190 PA and after 5 years i didn't had any space for them to grow/play and the value that i've bought them didn't had much return. I know i was being greedy, but it turns out it ruined not the save, all FM...
