I've just started playing the first season with Sao Paulo. But I'm unable to offer contract to players with expiring contracts to make Bosman Move. I tried to start in other leagues and am having the same problem. Does anyone have similar problems?
The exact rules involving bosman transfers vary according to the league you're active within, within Brazil you can only approach players at other Brazillian clubs the day before their contract expires.
(this is not a bug - just the way it is in that league I believe)
