Already sold a regen for over 60M. Was hard because he was a club icon, but needed space for younger ones.
But my better return was Tiago Dutra. Brought him from Villarreal for 80m and sold him to Goias two seasons latter for 3,5M. I was Internacional.
Iam not good on math, someone can calculate my profit margin?
In the same save, i brought a regen from Bahia for 2,3M, and already upped his release clause to over 60M. He will be worth even more in a couple of years.
