Made a little tweak to this tactic, won champions league 2 times in a row with Juve. Flaws: midfielders not scoring much (but besides szobozslai i don't have very offensive ones) e conceding too many goals sometimes. I suggest you to switch the mentality to positive when you play against good teams on the road. Screenshot of the team is from the second season. My most expensive signing was dembelé from Barca (38m).
This tactic turns easy mode on in the game. Unrealistic results, its insane. Two straight promotions, and midway through my first season in the Bundesliga, my team is in first place, with a squad of players that would be on the U-23 squads of any other Bundesliga team.
