you put them in this file C:\Documents and Settings\Home PC\My Documents\Sports Interactive\Football Manager 2008\tactics
I play a flat back four, a defensive midfielder (sometimes making backward runs, to make 5 at the back). Then a central midfielder who can attack, two wingers, and two strikers. Usually use those tactics with any team I manage, and 9 times out of 10 it's successful. (Y)
I use a 4132 tactic with corners set up so my centre back gets in with all headers, im Leicster btw.....doing a better job than Ian Holloway sitting first in January.
I just use a 4-4-2 formation, only bought 2 players and finished 12th with Barnsley just 3 pts from play offs, even played Jacob Butterfield and Simon Heslop in last few games and they got 7's and 8's!
