Fixed.
We can also do:
----------------De Gea-----------
Rafael/Smalling -- Jones -- Rojo -- Shaw
-------------Carrick -- Blind
Herrera/Januzaj--- Mata/Rooney ----- Di Maria
---------------Falcao
This will never happen although it should. This gives us the most balance and would help protect the back 4. Could also play Mata on the right or left, he and Di Maria can cut in with Rafael and Shaw providing the width. I think it's strange that we haven't seen him try a 4-2-3-1 when he was using it just a few years ago at Bayern.
