2-1-4-3 with 2 defenders???????

or do you mean 3-4-1-2??????

Without looking at a screenshot of your team here's my guess as to whats going wrong

1) 3 at the back is something i've played since starting this game a year ago and its now a lot weaker than it was. Your team mentality has to be normal or defensive or you'll concede too many goals
2) too many arrows, take them off see if things get better
3) Although many doubt the importance of player stats (including me) if you have any players other than your goalie who regularly get 4,5,6 stats (Tom Cleverlys ) look to find a replacement

If none of this applies to your team post screen shots please
