This tactic is absolutely class with my Newcastle team. Last time I recommended a tactic has got to be for FM2005.
Some basic info (for those in need of it):
Spent some hours looking for staffs, scouts and physios. (The guide below can still be used for FM08)
MTK Training Guide and Schedules for Fm2007 - Topic Powered by eve community
Further I'm using Matts Training (from FM2007). Pure magic!
After that I basically just bought and sold players....
So, over to this tactic. I'm now on a 10-games unbeaten run, beaten teams like tottenham (away) 5-1, Liverpool (home) 2-0, Chelsea (home) 3-0.
Basically what I founf works wonders, since I've found this a attacking for mid and lower teams, is that I try wait until I've scored my first goal, and then I make the following tactical changes:
mentality: middle (normal)
creative freedom: (normal) but just above little.
Tempo: (normal) but just above slow.
and the rest, keep it as they are.
Now, as a last tip: keep in mind that the DMC, AMC should be subbed during the game, as they tend to get tired using this tactic.
And... Last, but not to forget... I'm running the beta patch update
Hope this helps you
