I keep conceding a lot of goals despite wins narrowing my GD margin and also matches of close draw I lose out.

my league table



I use 4-1-2N-1-2 narrow diamond mostly and sometimes switch to 5-3-1-1.
Mentality - normal
Through the middle
whole pitch
mixed passes
force counter attacks
no offside traps

My DEFENCE has rating of mostly 7 and few 8 and rarely 6
and most of the time they keep tackling and blocking as it shows in match comentry
my keeper too is good enough ( 4 star rating and one on one stopper) but gets rating of 6 and 7 makes quite a bit of saves.
I may be just frustated but u tend to get frustated wen u are sailing with alead of 3-0 and suddenly in last 10 mins its comes down too 3-2.

please any suggesstions. oh and yes my defenders are 5 stars and two are three stars (one of them is DW)
