What do you think of 4-3-3 ?

[HeavensAAA]

Since your 3 midfielders are MCs (the MC/DMC is supposed to change to 4-5v-1 when needed), your team would be fine in MC area as long as those 3 MCs are placed flat in the middle. The earlier image suggested that you may have pulled 1 of those back and pushed 2 forward, hence the 4-5v-1 comparison.

3 MCs weakness would be facing flat-4 (flank) or diamond-4 (middle) midfield formations. The solution is either having ML & MR on the bench, or starters AML & AMR have additional roles of ML & MR (AML/ML[R]), so both wingers could just move back to control midfield when needed, and then 1 MC move back & 1 MC move forward to take full control of the whole midfield for possession if needed.

2 more separate notes:
1) wingers aligned with ST may be better off without arrows as they could fall onto offside traps easier
2) fullbacks may be better without up-arrows as no-arrow would allow them joining attacks, as there could be too much space on both flanks for opponent’s counter attack via wingers
