Another thing you can do if you wanna be 2 seasons in the same level, (or you wanna do this sistem usually) is to add as a friends teams of your league. next month they will win a level, and if you do this sistem, one day, they will be 3-4 levels better than you. And, this is the moment to see who use money to buy players of 6 stars usually... because if they do that every season, the players they buy (bought) 3-4 seasons ago, are worst for their teams at now, but, for you, his worst players are players of 5 stars that maybe (if the manager is a good guy), will sell to you if you do a good offer.
(well too if you have good facebook friends with high level and playing in the same server u can do this)
As I said, a player without money, but with patience, can win a treble or a league + champions easy.
