I absolutly agree. Choose someone from your country.
A person that would have a good reletions with the NT coach and that would encourrage managers to train players for NT. Don't look for a solution in dump IV or III european leagues. They may have some more experience in bb but Barbados U21 will be for them just an another challenge and non the greatest honour.
Only people from Barbados can feel the heart beating of your NT. Only they can engage themselves fully.
