I have found playing a high defensive line with no tight marking the best too go on this patch, What tended to happen when i was playing tight marking was that my defenders where getting too close to the opposition and they where just getting out ran all the time. With no tight marking and a high Defence line the opposition will still look for the long ball but because my defence is a few yards off the opposition ST it gives the defender time to get the ball and recycle possession to my team. Great tactic.
