Long balls over the top

Does anyone know how to stop conceding so many goals/chances from long balls over the top of my defence consistently in every game? I play a very high line with extreme pressing, and offside trap, yet still seem to allow the opposition through in goal from long balls. I have also lowered my back line to try and stop this yet it still persists.

Lower defensive line
Put mark tighter instructions for your centre backs
It is better to put regroup when losing possession
Offside trap on
Better to have good acceleration and pace for your defenders
Sweeper keeper on support which is good in one on one

You've said your whole problem in your question. If you play very high line all it takes is one ball and the striker has loads of space behind the defenders.
I also play high line but make sure my CB's are fast. Also change your keeper to a Sweeper keeper because he will come out faster to meet the striker
... But yh, playing a high line and pressing is a risk. You can put teams under pressure but one pperfectly excuted counter and you're in trouble

both are right but also wrong because of the set-piece tactics don't work correctly it doesn't matter what changes you make you will find that from most your corners and attacking throw ins you take you will see that there are only ever two defenders, even if like me you always make sure there are more defenders in my S/P it still only leaves 2 back so you are constantly worried about counters.
