Each tactic has his own level of consistency to put it this way.TFF like his name says dedicaded his time alot into this game and indeed he created some beautifull tactics.But the sad thing is that ME will nerf down this tactics if will work too good for you as a small team you should not be allowed get succes straight away despite the tactic u use.For example there are some tactics that break ME CCC barrier(Brasil tactic included haha) and what does ME to compensate this?ofc will make strikers miss and the frequency of loosing games with higher statistcs becomes really ridicoulos compared to real life.To be succesfull in fm 2014 u need take baby steps from your small team till u reach a "Barcelona" team both as reputation and with high stats players to can have finally a good consistency.
