I'm an old hand at this game. start of as Halifax and choose 5-3-2 sweeper with everything else on normal (passing etc).
I used to start of a 2 player game and choose halifax and dagenham, then would bleed dagenham for their best players.
Also keep starting the game if you get a good 1 scout or less....a good 2 scout lets you buy out of the 3rd division.
If you come across another team playing 5-3-2 sweeper, they can be a bugger to beat...the best formation i found to beat it was 5-1-4 long ball with passing high.
