What about this:
4-3-3, or 4-2-1-3 depending on your preferences
-----------------Johansen-----------------
Iraola-Brillant-Harnandez-Matarrita
--------------Bravo---Pirlo----------------
--------------------Mix----------------------
Shelton-------Villa-------TT/Mendoza
Why:
-4 man back line allows for our FBs to go forward without leaving one single CB stranded on an island
-Bravo can help the CBs with counters when said FBs go forward, as well as covering for Pirlo, which is something we need.
-Mix can gallop and run about wherever he needs to be, and has some space not taken up by the Penguin.
-Shelton on the right has given us better results than having Mendoza in. I was high on Mendoza after his first sub appearance, but he has gotten progressively worse these past few games. Maybe stick him on the left since I also don't think TT does anything much either.
The weakest point, in my mind, with this formation is the Left Wing. Both Taylor & Mendoza haven't impressed much at all on either side. Maybe even stick Mac out there for his positional sense around the box and better soccer knowledge that TT/Mendoza. I'm hoping Harrison can come on and immediately go HAM on the left side, but I think that's a bit much to ask for.
I like this too, but maybe put TMac in for Taylor.
