Am I Using 4-5-1 Right?

[gtmsnba13]

Playing Against a 3-2-3-2 Formation with 2 DMCs on the wings. There was no other way to get around my squad I had to use 4-5-1 formation b/c of all of my squad's injuries. Are my tactics the best for this formation?

Team Mentality: Attacking
Focus Passing: Through the Middle
Pressing Style: Own Half
Tackling Style: Normal
Passing Style: Mixed
Marking Style: Man on Man

No Offside Traps or Counter Attacks
I put red arrows on my CM and blue arrows on my two CBs.

Do you mean 4-5-1 flat? Do you have any players able to play as AMs? I would remove the blue arrows from your DCs.

Yes I was playing 4-5-1 flat 'cause both my AMCs were injured. :/ And I conceded two goals and lost miserably. Dropped down two spots in my league. Even having home-field advantage and spectating the game (1K/1K), my defense was complete rubbish. I've since got another AMC and sacked some players to make room. Here's my current squad:
