I see that you had only 4 strong opponents in CL (Atletico, Man City, Dortmund and PSG)
You played 12 matches vs them and got 8 loses and 4 wins, at your screenshots I see that your wins were pure luck(by looking at the match stats) because you got dominated badly.
As I said it looks ridiculous to me that someone makes any conclusion about the tactic's quality that he uses only after few lucky wins in matches where he got dominated badly.
In this game everything might happen and you can even win Barcelona with the worst tactic and with the weakest team but when you look at the match stats you always can say it was pure luck or not.
Anyway, there's no point in arguing further because it's obvious that we have different approaches to the game, I might say something good about a tactic only after I saw that I dominated the best clubs in the game with it and not just for few matches.
I don't say that this tactic is bad or good, I just say that making conclusion about tactic's quality after few lucky wins where you got dominated badly is a bit noobish becasue it's obvious by looking at the match stats that your wins were pure luck .
