well, this is bad management
Maybe those players gaining a lot but you 're gonna need a lot of greens to develop them.

I believe its more than enough to train a FT and bring one star up, I can train my 4* to 5* and sell him to gain club finance.
What is more important is to win titles and secondary the club finances.
It's a waste to spend greens only for developing and selling players.
It's much better to use those greens to develop 5* players so to be 6* and at the end of the season (when it's time for Cup and CH.L. semi & finals) to be early 7* so to have a slight advantage vs your strong opponents. That's what I do without spending a fortune.
A 3-4* player gonna need a lot of greens to be a 6*-7* player.

Back to the subject, this season I bought a 4* fast trainer (there weren't 5* nordgen in the market ) for one of my teams but this team was staying for 2 seasons in the same level and had some extra greens, also after promoting to the new Super League, gonna stay again in the same level.
I gave him an extra position and an extra sa using the new (with 3 whistles drills) and the old version.
In both cases I spent the same amount of greens (about 38).
