Kokodot,left wing i used isco, cazorla, ozil and lamela, all scored and assist a lot but try to have a left wing of that type, right wingers i prefer more the inside foward cuz they cut inside, someone like baloteli, wallcott, insigne, hulk, i tried both, right feet and left feet on the right wing and both worked like a charm, this inside forward most of the times is your second best scorer
I don't really comment on tactics, but the 영원&Anakin's Dynamic-real-tweak.tac, which was mentioned here and shared here is absolutely one of the finest 4-1-2-2-1 / 4-3-3 tactics out there. I have used a lot of tactics and somehow I am always interested in how the screen/videos/matches look and this is a really nice free flowing tactics where you can really build your squad.
I have played with besiktas, turkish premier league and reach the semis in the champions league, that is quite the achievement for a team like besiktas
I know this is not the place for me to comment on the tactic, as there is an original thread on FM-korea, but I found the tactic here and I recommend it to everybody. I had to delete FM 2013 as I started ignoring more important things, so have no screenshots for you guys.
