This is one of the best tactics I've done in FM ever. It's a very simple formation (4-4-2) but with little tweaks that makes it very special. Instead of normal fullbacks or wingbacks, it uses inverted wing backs in both sides; and it's strikerless because instead of using two pure strikers it uses two shadow strikers.

You need to have two complete fullbacks and two fast strikers (you can play your usual strickers there if they have good speed) and play left-footeds on the left side (your IWB, W, BBM/ and your left SS) and the same on the other side with right-footeds. The players have no individual instructions.
