macca i think the name of the tactic says it all really mate, its potentially very good. if you have great morale in the dressing room,the right players and good manager ability, this tactic certainly works. but without it, it can be pretty average.
for me this is part of the fun, i mean who wants to use a tactic that just works every time against any opposition ? then your not really a manager, your just using a tactic and going through the game without really doing anything.
i'll list the most important things for me.
1. good morale, keep the players happy by praising them and always be extra positive in pre-match interviews.
2. get the right players, pace & trickery on the wings, good concentration in defence, and good tacking & passing in midfield.
3. get a good scout with high tactical knowledge & tell him to scout the opposition always, this helps you prepare.
4. target opposition players with low morale and/or low concentration. for example if their CB has low morale and you close him down & tackle hard, he will make many mistakes and your likely to score more easily.
not sure what else to say
