Ok, I am not very conviced about formations with 3 defenses (my followers know it lol), but lets put the "base" in the idea that every formation can perfectly win a treble. Doesn't matter what formation.

Players performance can change if, you buy new players, or you change their positions.
I think you have 2 good ST's, not bad really. But this AMC numbers don't help a lot. you can prove in this position another MC or ST perfectly.
For a more stable defense of 3, I woud put 3 blue arrows, and some red arrows too (well really I play with 8 reds lol).

Mustafa and Mohgoub positions can be tested by other players, and will be good if, you plan 2 strategyes, a basic orders + a 2nd group of orders for if you don't have the control of the match. like attacking+mixed passing as basic order and very defensive+long passing and for the flanks as 2nd option (for example)

Test to find 1 man for corners and 1 for fouls will help you for sure, if you can find the correct man you can save lots of points.
And substitutions after 2nd half are always a good option when you see a player failing continously or one player don't appear been ST/MC.

Then think in Lopes and Vyalchinov to play or to be used as subs when your players dont do the work. I still thinking that meybe you need some new player to complete the group, but testing and doing some changes your team can go in a better way.
Till here my opinion lol
Good luck^^
