Still, it was great though the false 9 struggled to score much (around 10 goals per season), therefore I didn’t share the tactic with the community.
Recently, I have restored Windows and came across this tactic. As it turns out, it still works well. I've only made a couple of changes, and I think you should really try this monster.
The AML / ML takes the left corner, while the AMR / MR takes the right corner.
Set individual training according to the positions and roles of tactics!
Tested it with RBL and ManUtd, no freezing and no transfers; just set up the tactic, and let the assistant manager handle the friendly matches.
If you try this, share your results in the comments.
