if you plan on selling any player`s then sell on first day of new season as the market goes mad with bidding and you might get more money for player where if you put up now then you might 1 or 2 bidders and get around player`s value, also be careful in bidding in first couple of day`s of new season as you really don`t want to get into bidding wars, try and leave for a few days when it should settle down but still keep an eye open even watch a couple bidder`s to see how mad they go with the bidding
