I dont think there is one.
I am also desperate of a tactic that will give me first of all solid defence.
So that i can depend on it and focus on squad building and other managment duties.
I hate exploit tactics, i hate winning 5-2 and 7-3. The tactics uploaded here and there will give me big margin wins in most of the matches, but there will come the day that i will be completely smashed by a better and quicker team and because of high defensive line i will have no answer to that.
I want ONE tactic for all competitions that will give me easy 1-0, 2-0, 3-0, 3-1 wins because of solid structure in the back and good use of the flair i have upfront in my league agaionst poorer opponents, and pure solidness in Champions League.
I also dont like shoots and OIs. I want my team to have the best solid structure possible, and if i lose its ok. I will know that next year with two or three transfers i will be better.
And i dont ask much there was some tactics with this philosophy that actually worked in previous patches.
Anyway last hope is Hazza's try of Greece 2004 tactic.
I am trying for a long time to built one myself but i cant find the balance. Either it doesnt work OR if it works it has more balance in the defence and when you conceed a stupid cross, corner or penalty you struggle then to turn over the match. The bold is why i find a stable solid defensive tactic imposible to work in FM. The only way it will work is if you have world class defenders with great positioning, strenght, jump, concentrations, decisions, aggression, composure etc.
Best defence is attack in this game only. I hope someone proves me wrong.
PS. I found out that loose marking and hard tackling to all players seems to work. They keep their positions and tackle hard in the correct time. I experiment now with closing down to see what happens. but i dont have the time the knowledge and the patiense to make it right.
