Still a great tactic, and even if you make a tactic with Man Utd, you still have to make it awesome, look irl, man utd best players bad results, i say make your own tactic with a lower league club and then we talk further,
for 5 years i'm testing al kinds of tactic with only Feyenoord-Toulouse-Sankt Paulie and FC Koln,
so if it works, it doesn't matters what kind of team you play with no.
