I don't think the training makes that much difference to the tactic, but this is how I set up mine (after the tactic is fully fluid):

I just follow my scout's recommendation on match training and I set the player's individual training to whatever role they're going to be playing. You will probably have to train your full backs to wing backs because there's a severe lack of good, natural wing backs in the game.
I have played x1 season with this tactic as Chelsea, Won the league by some margin, lost FA cup final and CL semi final on away goals, other than that very impressed, Cech won Golden Glove as well.
Gunna try into 2nd season and hope it remains top notch.
