The only thing I did was actually to move the two wingers in as DLF(att.) on either side of the striker. I used Att. movement match training and general training balanced average.
Against top teams and hard away games I change mentality to "Counter". This actually worked so well I'm going to try "counter" in every game from now on.
I don't know if it has any effect at all but I also started setting opposition instructions myself before every match, but only following my assistants one advice. ("move david silva to weak foot)
I also have fast CB's and it seems to be important.
That's all I did and it gave me the best results until now in '15 and also very nice football to watch. I know I'm a big team with a young but very talented squad, I have not tested it with a weaker side yet so I don't know how successful it will be with a team like that.
Would be interested to hear how it works for others.
If it's okay for the thread owner I can put the tac up here.....
