I think this guy is not a palestinian. He just wants to support this country for some reason. Maybe he wants to change his nationality in the game so everyone can see him that he supports the palestine even though he is not a palestinian.
As i know it's very difficult to log into this game if you are from palestine.
I have a friend from israel who live near the palestinian territory.
we become friends when i have a temporary job in muscat (oman). He also play top eleven.
But while in his hometown he always uses vpn app to play this game. because he said you can not login to this game without using vpn app or without change your ip address.
So my suggest is try to contact
support@nordeus.eu regarding your question.
I'm not racist by saying this. I'm a kopites and i only support my team and liverpool. not others!
