after struggling along for three seasons with my birmingham side and using loads of tacitcs on these and other forums,i found using the default tactics work fine.
i didnt want to over complicate matters with the sliders so i left them all in the middle and just changed to different formations depending on who i was playing.i sometimes used the counter attack or offside options to try and gain an advantage.
with regards to the player intructions i left them alone thinking if they all think along similar lines they will gell as a team quicker and get a better team understanding ,what do you think
