I really don't understand the logic of bidding on 3* players... yes they can work on the lower levels of the game (when most teams are rubbish and inactive) or if your the highest level on a server (3* market to bid on) but other than that you may as well buy 5* since lower level managers will see those 3* players as 5* players, plus its a waste of time chucking extra greens on a 3* player when you can bid on 5* players or buy scouts.
