Developer of this game have got lot more to do make this game exceptional. We don't need to buy player with coin and then release them for nothing, if one need to have a lot of coin to buy a player, he should also make lots of coin for sell them. Coin and diamond should also be exchangeable. It's so bad that you can't search the name of the player you want and sign them except those displayed for purchase by the game itself. The last version also seems a bit manipulative, more work is needed
