I think if it wasn`t for his untimely injuries and suspensions we would have seen him in that position more often. I for one really support a 3 CB formation. We have the mobile full-backs and 3 top class CBs, I don't get why we have not given this a shot.
This is what I would field:
------------------------------------Karnezis----------------------------------------
-------------------Manolas Papadopoulos Sokratis------------------
Torosidis-----------------------------------------------------------Stafylidis
---------------------Samaris-------------------Tachtsidis---------------------
------------------------------------Fortounis-------------------------------------
---------------------------------------Donis---------------------------------------
------------------------------------Mitroglou-------------------------------------
