I have been having huge success with this tactic & find it by far the best tactic available.
Just thought I would share a finding that I haven't seen posted yet.
It relates to getting the most out of the MCa position, I know people have had little bits of success in giving it the free role or trying to make the player arrive late in the box to score goals. My success in this area has been to find a set-piece specialist for the role, in my case I signed Nakamura, in my current save he has 20 for free kicks, 18 for crossing, 18 for corners, 18 for penalty taking. The results of this have been a few goals direct from free kicks, but the major difference is assists, he has provided loads of goals from corners and free kicks out wide - they all seem to land straight on the target mans head.
