The results are good, but it's important to have the right players. And needless to say, you need to give the tactic some time until your players familiarize themselves with it.
I tested the tactic with RB Salzburg.
This Mourinho inspired FM20 tactic was used for 2 years in-game and I've managed to win everything that could be won with RB Salzsburg.
Let me know your opinion and share your results.
