Some suggestions on RJSlow's recommendation

Play either full pitch or hard tackling. Unwise to play both or your condition will drop fast.

For formations with AML/Rs better to use short passing.

Remove the red arrows on DL/R if you are losing possession.

Zonal marking. I'd use offside because my DCs are able to pull it off, so this one is up to you.

That's just me and my two cents.
