Although Coyne was signed from non league, if I recall correctly he had been in the Manchester United youth team which was how Macari knew of him.
Does Kirkman count as a signing from non league given that the Welsh league is probably below National League standard?
Yes, he played 2 games for the first team scoring a goal, then went to Crewe for 4 seasons, Hyde United for 3 more when Lou Macari brought him back into League football.
