Having a staff around to help is very important, to be able to scout the opponents, the players that could be material for the NT, and to route properly the training of the youngest players that can still pop quickly.
And also, the coordination with the U21 is very important: save young talents is vital for small countries like Ghana, and often the NT has to sacrify results in the short run to let the country have a bunch of good players in the long run. This is done by using slots for players going to retire due to almost-bot teams.
