Buying players and fees

[Ro Edu]

I bought a player about 2 days ago but squad was full so I sold another one to make place for the new one. When I clicked on contract offer, it said the player will get 21000$ per season and a one time fee of 159000$. Why is that fee applied? Is it random as i don't recall seeing this when I signed other players?

Because when you transfer a player you pay only his ~value , but when you don`t have space to sing directly is like renewing his contract ! When you want to sign up a player from auction make sure you have space for him , otherways you will repay the contract !
