2. Niall McGuinness 24, (Rhyl FC)
At just 24 years of age, Niall McGuiness is the winner of this countdown, managing the Welsh Premier League side Rhly FC. He had earlier been the Academy Director of the club and it is very interesting to note that his father Laurie, who was formerly a Rhyl coach himself, now serves as the assistant manager to him. Perhaps this is one of those few instances where both father and son share the driving seat of the football club. The two were appointed when former manager Gareth Owen and assistant manager Mark Roberts were asked to resign from the position. The team also suffered their biggest defeat under his leadership, losing 0-10 to The New Saints in August 2016.
