Depends.. if you get the most quality players in the market you will be fine,i mean if you are level 4 you need 38-39* players,level 5 43-44* players,level 6 48-49.
Im level 6 with avg. quality 45.3.. since we dont know our League opponents yet,from what i see in my CL i have the best avg.quality.
Well if you want you can get Scout players and yeah..
