After answer you Ive been thinking that maybe I was wrong thinking that you had a problem with your players and that maybe you're loosng many matches...
Don't looks like this looking these players, whats count in contribution terms are goals, assist' and MoM and MoM are really well share in your 11 with 25 in total....
I think that your question is more related in another sense true? despite you win maybe you would like to see a ratio of improve in some sense or that how better is the player more should accomplish the orders? when you say worked 50% is not that you lost he 50% of matches true? is related more to what you expect...
Well I see initially some good players, really I don't know the level of your rivals but, really, don't seems you have to have many problems. xD
In this case, the most important is find the way to have the control of the match, despite in my 50 seasons I used the same formations (4-3-3, then since season 12 the 4-3-1-2 and now a 4-2-3-1) I usually have 2 groups orders and I do just movements moving players 1 line or switching them.
Maybe can work for you a 4-2-3-1- as I have and as I do (today did it and worked with 1 goal the ST and then2 the AML when switched their position) and you can try depending of how it's doing the ST and AML change their positions as seems that are good players.
In my case I start matches playing attacking mentality and long passing, both flanks and usually I change this to focussed right-left depending of how I see the activity of ma players.
My second orders group is with very defensive and I put in OFF the counters and offside that start in ON mode, this second option has saved me lots of points really.
And well, more or less thats what I can say by my side, you have some opinions and you should see how really your team plays better and what option work
