I don't know how to counter it, but I had a lot of success once with more or less a similar formation. It seemed like my AMC got several breakaways. I often got into a situation where I attacked with 4-6 players on a wide line, and they put the ball behind the defenders and I could score. Can you fight that risk by not pressuring hard? By not using off-side trap? Or should you in fact pressure hard?

If nothing else, let us know what your conclusions are after the game!
