This is my 4-2-3-1 Wide tactic for Football Manager 2021 that I have used with Dortmund.
This tactic has given me great results.
It's not a possession based tactic but allowed me to the the best defensive and offensive team in the league.
1st season we won the league, 2nd we won the league, domestic cup and champions league. Beating PSG, Liverpool, Juventus and Bayern.
The 2 MC are on support so you are not exposed in the midfield. They also interchange with each other.
When you don't have the ball the AML will mark WBL, AMR will mark WBR and the AMC will mark DMC.
This is why you lose possession but keep a good defensive record.
Here are my 2nd year player and team stats:
