Negotiations Window
From the upcoming season, direct transfers through Negotiations will only be available during the last week of a season. The Negotiations Window will be open from the 22nd to the 28th day of a Season. Making or receiving offers for players will not be possible outside of the window.
Who ever bought a player the last week of the season unless he stayed in the same level ?

Buying players for some training and then selling through negotiations, was giving few extra tokens to active manahers.
Now is gone.
