its quite common to narrow tactics. 4-3-1-2, 4-1-3-2, 4-1-2-1-2, 4-2-2-2 are usually better at tackling with a deeper defensive line because your CMs will be brought into defensive action.
Been having much the same problem with my* favourtite 4-3-1-2 (a 4-1-2-1-2 in disguise, the center CM sits a bit a deeper than default), but i also got from the AMan that we seem to play better with a deep line. Did it. dropped it a lot donw to where the scroll chages from deep to normal.
Pay attention to the game and see if their forwards are either stuck with your defenders or midfielders.pressing higher helps, but Keep in mind that it tends to wear out the *CMs at ridiculous speed and still the opposition wide players will s a lot of time and space.
But i really dont care that much, because narrow tactics are great at soaking and keeping the wide players wide...shut from the box!!
