Above those levels financial management becomes more important than before, In my level in order to keep a 17 players team you need only for salaries around 800M per season. I tend to have a short team and resisting temptation to buy new players for positions i allready cover satisfactorilly, at the same time i play occasionall (to minimize injuries) friendlies.
