I'm scoring lots of goals, and doing relatively okay in the league, but I'm conceding a lot of goals with this tactic. Something like 1.8 per match in PL and even more in Europe. I'm Liverpool, starting back line of Enrique, Coates, Agger, Johnson, with Lucas in the DM spot. I'm conceding goals even when I invert the midfield so Lucas is in the deep holding spot and the style is set to defending.
My training is on Defending, high intensity, I'm using the OI Dave posted, close down defenders, weak foot wingers, tight marking and close down on strikers, midfield creators close down and hard tackle. Not sure what I'm missing. Just took back to back 1-4s away at Juventus and Tottenham.
