A coach in the Nigerian professional football league with CAF B coaching qualification wants to get coaching qualification from Europe. (Preferably England). What do I advise him. If he chooses England. He has to start from level 1.
There still should be an international coaching license which the English FA used to run for overseas coaches coming from outside EU. You may ask for that.
Not sure if Scotland do an International course. Ireland North and South both do International. Not sure what qualifications you need for either.
