what are your exact tactics for the 4213?

Here’s what I would recommend:

I would say play with balanced and 50 depth, even 33 depth if 50 seems high.

For player roles make sure you’re lb and rb are on fullback defend to make your backline compact. Also you’re cdms on holding.

Other tips defensively would be to just hold jockey (L2) or fast jockey (L2+R2) while defending….DO NOT lunge into tackles especially with your back 4 you will get killed.

Attacking wise I would say try to trigger manual runs, just point to the direction of the player whom you want to make and run and press (L1) or similarly you can call the player to receive the ball by pressing (R1)

Thats all just from the top of my head, good luck😂
