4-5-1 v

[lopata97]

Hi, I play with 4-5-1 V formation but always losing against teams with similar %, even with teams 10% worse. Today I lost 0-4 against team like mine. So I want to know where is the problem, here is my tactics:
Team Mentality: normal
Focus passing: mixed
Passing style: mixed
Counter-attacks: no

Pressing style: low
Tackling style: low
Marking style: zonal
Offside trap: no

Also, can You send me a screens of correct 4-5-1v. I have now 4 defenders in straight line; is it ok?
Maybe issue is in my tactic? Maybe 4-5-1v is just bad and I should change it to something else.
Thanks!
