To get the tactic to work at it's best it's important to choose players with preferred foot the same as the side they're playing at (the advanced forwards almost work as wingers), a tall target man and your best header on near post corners. Otherwise it's almost plug and play.
Cruising through the leagues from level 10 in England, I thought I needed to see if I could get the same results in other leagues. I therefore chose teams predicted in the middle of the league (if there were 24 teams I would pick the team predicted as number 12), and even some predicted for relegation.
I only set the tactic and went straight on holiday for a season, with no transfers and no choosing of players, leaving it all to the assistant manager.
