Do We Really Have Coaches In Nigeria: ?

It has been very long time Nigeria has been peddling sham-coaches to herself or to other nations in the continent. But the question is 'Have we ever had a coach, or Do we have a coach in Nigeria? Especially, when we talk of a competent coach to win or duel a (tough) match. This raises questions like:

  -  Who is a coach?
  -  What are the criteria that make a coach?
  -  What are the duties of a competent coach in the field during a match and outside
     the field?
  - What are the para-experiences that must be possessed by a coach?
 
      For more guidlines:

  - Onigbinde is a trainer for discipline and selection of players to be a team. He's not a
     coach yet.
  - Eaguavon is a trainer built on past experiences and fielder. Yet, he's not a coach.
  - Chukwu is a rehearse trainer built on old experiences. Yet, he's not a coach.
  - Shuaibu is a trainer, fielder and a lucky dependant. Yet, he's not a coach.
  - Siasia is a trainer and an emotional fielder. Yet, he's not a coach.
  - Daniel Amokachi is an emotonal trainer. Yet, he's not a coach.
     So well of Fani Amu and the others. They are football lovers. Some of them maintain
    one or two of a coach criteria and lack the rest.
