My first tactic is in 1st page and it's the base tactic that I have created and from it, I have tweaked the other tactics likes v3, v4 and v7 One. Let me explain a little bit.
1. Tactic Man Utd Patch 9.3.0
A first tactic that I have created and it is great for me because I have won a lot of trophy from this tactic in the 1st season. I have showed the screens about my achievement by using this tactic. It's works well.
2. Tactic Man Utd Patch 9.3.0 v3
A tactic that I have tweaked a little bit at the midfielder and striker position. It's still works well but many people complain that the strikers didn't scores a lots of goals like first tactic.
3. Tactic Man Utd Patch 9.3.0 v4
So, I have created v4 that I tweaked midfielder and striker position too. I have made an experiment on this v4 and my strikers scores more goals with this tweaked instructions. The result is many people is satisfy and glad that v4 is working well. Also, v4 is better than v3.
4. Tactic Man Utd Patch 9.3.0 v7 One
I have developed a new tactic (v7 One) because I was read the thread "Goal machine" by Ma-Li that he use Ronaldo as a striker and got 70 goals from him at the 1st season. So, I likely to make Ronaldo as my lonely striker with a shadow or support by Tevez, Rooney and Mata. So, by looking at this tactic, I only put one striker at the front. The result is, my lonely striker (Ronaldo) scores about 55+ goals for every season.
That's working very well for me because my team scores a lots of goals and conceded a little goals. Until now, I have used this v7 One tactic.
5. Tactic Man Utd Patch 9.3.0 v7 One Latest
My latest tactic after v7 One and I have tweaked the MC instructions depends on my players abilities.
Conclusion.
v4 is better when you want to use 2 strikers. if you want use only one striker, v7 One is better.
