how did yall get so good, experimenting tactics?? and stuff

all i know is, i do so-so, i play with Arsenal and AC Milan, i usually come runner-up in EPL and 1st or 2nd in Serie A, i do ok in the CL, not win tho, and, my defence if quite leaky, BUT MY PLAYERS MISS TONS of chances, the literally miss the goals, like 50% shots on target, do u ppl mess around with the with-witout ball screen in tactics?? etc, someone with some hints or good advice?

i dont class my self as an exellent but im classed as world class on the game :p i do fiddle round with the with/without ball stuff but if ur only an amateur then i would not go near it cos it can confuse some people very easily, personally i would not manage to teams of that quality because u cant concentrate on gettin one to a world class level, ill send a screenshot of my team soon and u will be amazed at the talent i have, im bolton, man u and england (bolton WERNT top class then:D )
wats ur line up at the back ive got emerton dmr, lauren dc, samuel dc, lythe dc and bouma dml.

i am Arsenal and AC milan

Arsenal : Ashley Cole, Keown, Sol Campbell, Ivan Cordoba

Milan : Maldini, Laursen, Coloccini, Kaladze, Roque Junior

and DMC are Vieira and Gatusso for ARsenal and Milan respectively, and, i just started new season and i'm good in reputation, by next season, i'll be world class, LOL

I have taken Farnbourough and Reading to the top, I have won the champions league for 6consecutive seasons with Rangers! Now I'm going for the Welsh league with Caenarthon Town!!! No money and no reputation hahaha its impossible!

I've only acheived sucess with Newcastle:
Ive done a domestic treble, double-double and brought some old masters to the club.

Ive started again with NUFC and currently lead a four-way title battle.
