what i would like to know is which is the criteria for the player to choose
a team. Because i was certain that the wage made the difference and now i realize that i was wrong.Anyone knows?

It is the wage and the contract length, but the higher wage should always get the player according to the current rules.

Hi
I thought too but look the mail i received:
Sidney Monteiro has rejected your contract proposal (wage: 30999, seasons: 1). He was hired by Náutico
And his present wage is 25315. So is it a bug?

Oh, this is because Sidney Monteiro was put back on his original team, the way he was fired/let go was considered cheat.
