I personally never spend my whole transfer budget, instead what I do is put whatever budget remains into the wage budget. Doing it the way I do I've found the board give you more money to spend as the seasons go on. Free Transfers and younger players means even with more money I have little need to spend anymore then I do in the first season, essentially I just keep ploughing money into the club whilst remaining competitive on the pitch.
You mean the add and remove leagues feature? Where you can change which leagues are active at any point during your career? FMH is superb as it is, ok it needs a few changes to stop it being same old same old but if it keeps adopting stuff from the PC version than it won't be any different to the PC game after some time.
