Let me explain to you. NORDEUS it's a serbian company as I know. Serbians funs of Red Star and Partizan have good relations and similar shirts Red Star/Olympiakos and Partizan/Paok. So they want to attract (for customers) funs from those greek teams. I 'm from Greece and I know. So that's why I bought this crest (look at my recent thread) cause it look likes the flag of Greece.
and REAL or ARSENAL doesn't care (at the moment).
