Many thanks JP - fantastic tactics.
Been using this with Boreham Wood from the Npower League 2 (after 3 or 4 games with 4-3-2-1) following promotion from the Blue Square Premier. Finished 2nd in Npower League 2 and am now top of NPower League 1 at mid-season.
Prior to that I was using flat 4, 3 centre mid, 2 attacking mid wingers and 1 forward and this got me from the Blue Square South to Npower league 2. I always loan the best possible 4 or 5 players long term and add around 6-8 3 month loans throughout the season to cover/plug my tiny 15 man odd squad. I also scower the best free transfers (John Bostock, Ruben Lameiras, Bradden Inman, Conor Coady, Alexandr Geyrinth, etc) extensively each season so I tend to think I end up with a small but relatively strong squad. This and selling them at profit one or two seasons later is necessary to keep the costs down, balance sheet positive and standard of players up season after season. I also think rotation and squad harmony are massive in FM13.
I think I will need to change my approach should I reach the Championship as good enough free transfers might be more difficult to acquire (more scowering I guess!) but will be sticking with this solid formation for a while. I will try to post some screens if I can stop zerging through the season.
Glad you're enjoying the tactics. Dont be in such a hurry to change if you're promoted. Sometimes you give yourself a better chance attacking teams rather than sitting back and getting beat. Look forward to some screenshots if you get time.
