I've been a fan of 3-4-2-1 since it provide box structure in posssesion like City's.
also, I like your philosophy as well and want to replicate it but the only problem is I choose to manage Tottenham and the CF (yes, he is not transfer yet) is Kane w/ PPM come deep to get ball.
so,my question is how should i create a 3-4-2-1 that have a CF w/ come deep PPM (actually Kulu got it too).
