What are the best tactics to use Narrow Diamond?

[Shield]

I have played narrow diamond from season 1 through to 12. In seasons 1 till 10 I won the league comfortably every season without being miles ahead of the rest (I was always the best avg rated team though). Last season I was 8 skill points better than the next best team in my league but only just won the league
W17 D6 L3. The ratings of my players were all good except my DMC and MC positions who seemed to get 4,5 and 6 ratings week in week out, no matter how much I rested rotated or swapped position for these players they just didn't perform.

This season seems to be going the same way my squad is clearly the best in the league but is starting to drop points.

Either the game engine has changed or the new players I have brought in don't suit the formation. I decided to bite the bullet and replace my DMC's and MC's to see if this makes a difference. I will post back with the results.

I have noticed other teams I am friends with who have played the ND long term seem to be struggling in the same way also so I suspect it is more to do with the game engine than the formation.

My tactics have always been;
Mentality - Attacking
Passing - Through middle
Pressing - Whole pitch
Tackling - normal
Passing - mixed/short
Marking - zonal
No counter
No offside

Recently while experimenting I have found the same tactics with defensive mentality and force counter have brought me much better results and a lot more goals.

Do you put the red or blue arrow to the players?

Do you put the red or blue arrow to the players?

Blue on DC's, red on AMC.

I have tinkered about with various different arrows and orders but it never seems to change things much.
I have noticed the AMC scores half of my total goals per season.

you means like that?

Yes, I do occasionally put an arrow on the DMC as well. Having triedb both Att and def arrow I think Att is the best option in narrow diamond my DMC seemed to score a lot of goals from distance that way.
