I tried this. In FM 12 or 13 I downloaded an expanded German league and picked Dynamo Berlin. I always found it curious how Berlin, one of the biggest cities in Europe, don't have a major team. So I thought, with such a large population a consistently successful side would become one of the biggest teams in Europe.
Well.. yes and no. It took 30 seasons, 15 league titles and 7 champions league titles to fill a 40k stadium.
The biggest problem is money. Going from part time to full time almost bankrupted the club, the increasing demands of players and staff as you creep up the leagues is impossible to deal with and the only real source of income is selling players. Although it does give you a lot of pride seeing the national team filled with players that once played for you, its mostly f***ing annoying. The first decade was just crises management. Played half my first season in a third tier with half my squad made up of youth players, loan signings and freebies. It was just horrible.
It's only when the sponsorship deals start rolling in that you get a sense that things are turning around. Which was the 4th season in the first division. I could keep my players and staff and even splash out on a new signing.
But then the board decided to build a new stadium. I looked forward to that moment. But when it came, it dawned on me that it was my transfer budget for the next 5 seasons that was paying for it.... FFFFFFFFFFFFFFFF***
