Here's the first round of players making it to the Netherlands according to sport24. InPAOK posted a list that was missing people like Matos and Vieirinha; goes to show you the quality of reporting.
Γλύκο , Πασχαλάκη , Ρέι , Σιαμπάνη , Κρέσπο , Βαρέλα , Μαλεζά , Χατσερίντι , Μιχόγεβιτς , Βιεϊρίνια , Λεβέκ , Μάτος , Κίτσιου , Χαρίση , Μουλέν , Μαουρίσιο , Κάνιας , Μπαλογιάννη, Σάκχοφ , Λάμπρου , Ενρίκε , Λημνιό , Μπίσεσβαρ , Ελ Καντουρί , Πέλκα , Μυστακίδη , Κουλούρη
Jaba will obviously be joining, once he is officially announced. And presumably Warda, Prijovic, Pukki, once they are available. Markovski wasn't chosen, so I'd expect a loan to be announced very soon. Cool that Balogianni is there, though I can't see him making the squad.
