I'm back to share my tactic.
It is based on my previous system from FM20, adjusted to play 2 strikers because strikers are so good in the 2021 version!
You can expect the same as before; high pressure, fast passes, asymmetrical system to provoke a lot of possibilities and danger from everywhere at every moment.
You will need a tall player as left striker to play tower control area (e.g. Lukaku, Ibrahomivic, etc any good tall player will be fine).
I also recommend a fast right winger right footed to force him to stay in the right of the pitch.
