It seems unbalanced and might really struggle against some teams.

If those are your best quality players I would try: Red arrows on DR, DL, AMCx2, blue arrow MC. Hard attacking, short, through the middle, offsides on (unless your DCs are below ~65% speed, if so, you can try adding red arrows to them, too; if that still gives up counter-attacks, then no offside trap. Full pressing, medium tackle,zonal, no counter attack. If you can't maintain near 70% possession, it's not working well, switch to man-man and try a while longer.
