hi Mike,
nice post mate.
i just want to share since we using similar tactic. hope u dont mind
i also used this kind of tactic since fm 10. its always works. but to be honest, its works better in fm 11 and surely its makes me kind of boring playing this, even only for 3 days only.
whats different between urs and mine is the way we put role and duty for most of them. whats i want to add is : u mention that passing is up to. this one is a hard case. i think in fm passing is almost the key for us to make our tactic works well. for exam, if my scout told me that direct passsing is best, then surely we must go direct passing on our tactic. using this 4-2-4 tactic, i have 3 kind of different tweak, its for direct, predominant in middle and congesty. using this in fm 11, i finish my MU at 1st, with 29 win, 9 draw and 2 lost. 116 goals with 27 conceded. i only lost in 6th in fa cup. win champ cup, leage cup. roney become beast 26 app with 30 goals 11assit and 5 man of the match. i only bought eden hazzar for my playmaker and dennish appiah for subs rafael in right full back.
i hope we can discus and share more in future, since i am really crazy about using 4-2-4 tactic
cheers
