"No, players who are a skill point away from 6* will appear on their respective levels. Your 4* a skill point away from 5* will appear to managers the level below you."
Not true according to my L5 negotiations, unless I misunderstand you.
1 skill point?
For instance there are four strikers on my list now all varying in age.
All 5* Avg Skill 44 43 43 42
The 44 has skill grades of 43.2 45.6 44.2
The 42 has skill grades of 37.8 44.2 45.2
I have five of my players on the list they vary between 43 & 44.
So could you explain what you mean by one skill point.
