I keep warning mamagers about buying players in, the first week an especialy in the first 3 days!, everyone wants to improve there team and so bidding wars are everywhere!, Don't bid in the first week and if you do set a limit of say 5T then stop if it goes over!, one of the best time to get players is in the last few days of the season when higher level players are getting rid off there weaker players because there weaker players are higher quality for you.
