i played in the russian league and barely had any money to improve the squad. then i struck gold with matias arezo (I didn't visit any forums so I didn't know he was a well known player) and a 18 year old brazilian dlp regen wanted by half the Europe, both on free. After I sold them for about 30 million USD, I started searching for cheap/end of contract deals, being able to afford elite young talent. Because of the specifics of the russian league, U-21 players didn't have to be registered, but after they turn 21, they either occupy one of the eight foreigner slots, or get sold. In about 5-6 years of doing this I accumulated about 350 million in balance and 500 million in transfer budget.
