Playing defense and using instructions

This could very well be me just not knowing how to play this game, but 2 years ago when playing Football Manager for the first time I had a problem and that was opposing teams would ALWAYS do through passes to their teammates where they have breakaways and score goals on me. I read forums, looked at tactics, tried different things but in the end I figured it was just cause I sucked at the game. Now, two years later apparently I must still suck because the SAME thing is happening all over again. It's either I don't know how to do tactics (although I'm using a 4-2-3-1 formation that fits my players style), my defensive players are terrible, or the through passing is very broken.

I would say that 80% of the goals that happen against me are from through passes where players end up getting clean breakaways. What am I doing wrong? How is this prevented? I have selected a more defensive approach and not to hassle opponents, etc but they still get beat by almost every team I play. Btw, I'm Luton in Skrill Premier.

Any advice would be much appreciated. Beyond frustrated at this point considering this very thing happened two years ago when I had an earlier version of FM.

Any help and advice here would be appreciated.

Just trying to figure out which instructions prevent the opposing team from always doing through passes which lead to breakaway goals.

Post your team details, formations, and tactics in the tactics forum on the site, you'll get far more help there.
