If you play with Instant Result then follow the tip that TFF gave at the OP about how to make the tactic work with Instant Result.
I easily won EPL with Southampton, the 1st season, used Instant Result all the time so I'd say it works great with Instant Result.
Well, it seems that I must stick with the game without instant result anywy, coz I am playing FM Touch and there's no OP instructions to set before the match starts.
