I've been scrooling through some pages now and I didn't found any info on this formation that I'm using very succesfully.

4-2-3-1

DR - DC - DC - DL
MC - MC
AMR - AMC - AML
ST

Red arrow on DR, DL, AMR, AML
Offensive
Short passes
Mixed where to play the ball
Zone marking
Normal tackling
No counter or offside trap

I'm a low 5 star team now and in first place after beating the first who has a middle 6 star team with this formation. He was playing a diamond formation.

Like I said, I've been doing well and hope to continue do well against most teams, but lately I've been thinking about switching to a offensive 4-5-1 V formation.
What do you think about this formation that I'm playing and how would you play to win against me?
And should I switch to 4-5-1 V formation?

Thanks!
