Why not just create Azerbaijan,or any other country for that matter ? Choose an unlicenced club team,transfer out any players who also play for a national team,then transfer in players from other club teams, (if you want a bigger squad).Remember to edit the players appearance ,stats e.t.c. BEFORE you transfer him in ,though ! The original teams name,flag,players e.t.c. can be modified to how you want them. I have created/converted many club teams to national teams. The only drawback is that you can only play your created team in exhibition matches, not in most cups and leagues.
