In every season I buy a whole new team.I keep the really good players who last season were 5 stars and now they are 4 stars.I dont keep more than 2-3 of them.The rest of the team is 5 star.I have seen other teams with scouts.I cant effort buying them in the scout list,so here is my question:

How can i get scouts except buying them in the scout list?
And 1 more question:
Can I have players with higher stars than 6 stars and if i can how can i get them?
