1.Stay away from it, it's not worth!
2.You should have every day, 12-16 hours before a match, cup, ch. league/super league/league, so I don't know why you didn't had this offer the last 2 days... but don't worry, usually these players are too expensive, not recommended for your level...
3.Lvl1 & 2 have their auction, no other higher lvl team involved, the rest of levels have another auction where everyone can bid on any player, the players cash price in relevant to their level,each manager sees the players according to the level they are.
