If I had to compare to a manager, I'd say I'm like Harry Redknapp, great at spotting a bargain, hardly every have any flops in the transfer market and like my teams to attack. Decent on making my own tactics, but need to learn a lot more about the defensive side of the game.
No preference for a particular formation, other than that my best results have always been with one man up front. I generally try to play to the strengths of an existing players in the side and adapt to them, usually keeping the same shape for future signings. I hardly ever sign stars, I go for wonderkids, but generally the ones who only need 2-3 seasons of work. I also make 'strategic' signings, if there's a bogey team that appears for me, I might sign the player that always does me over.
