Torosidis on the right & Holebas on the left are both brilliant crosses of the ball & Greece need to utilize it's strengths by playing them as wing backs rather than traditional full backs. Germany played that 3-5-2 or 3-4-2-1 formation at Brazil 2014. I've been saying this for a while now.
--------------------------------Karnezis------------------------------------------
-----------Manolas---------K.Papadopoulos------Sokratis---------------
Torosidis-------------Tachtsidis-----------Samaris-------------Torosidis
-----------------Fortounis-----------------------Fetfatziidis-------------------
--------------------------------Mitroglou-----------------------------------------
This I think would give Greece better attacking options & service for Mitroglou.
Before you all start jumping up & down about putting Fetfatzidis there, it's only a example. If you want you can change it with Ninis, Kone, Samaras or Karelis. It would be whom is fit, in form or simply playing at the time.
