Sorry, didn't work in any way in italian Serie C1 (great team) and Serie B (medium team).
Many shots, but NO goals, and many, many counterattack given to the opposite.
Tried changing instructions, mentality, but all for nothing.
I sorted out how to offer to such "impossible" players!!!
You have to go to the team screen (such Castilla, Betis-B) and offer the transfer from here :)
For me, it works always!
