Full backs not performing?

[christoon]

I wasn't able to find a thread on here concerning this,but if there is one,my bad.
I'm having a problem with my full backs,the opposition wingers and wide midfielders are consistently able to dribble there way around them and deliver in killer crosses and through balls.The full backs I have atm are Criscito on the left and Kaboul on the right.
Any help is appreciated.

Well Kaboul is ****. So buy a new RB.

Yeah that is true,tried to get srna but man united beat me to him

diego renan is cool too, i normally get full backs who fit in the attacking role and have them set to full/wing back (attack), run with ball either sometimes or often depending on their dribbling skill and wide play hug touchlines, then crossing to often from byline aim target man/far post. long shots either sometimes or rarely depending on long shot stat.

normally works for me.

serge aurier is quality for kaboul replacement

can't really afford a new right back yet.
They tend to be pretty good when on the attack, but as soon as the opposition get the ball they seem to just forget completely about the game and let players slip easily by them.Are there any tactical changes that would help them when they need to defend?
