At the top of the list is Simon Weaver who manages Harrogate Town which is owned by his father, Irving Weaver.
Not too much danger of getting the boot from there.
Blades fan Neil Warnock being considered to return to Bramall Lane take over from Slavisa Jokanovic at Sheffield United.

I realise Steve Cooper replaced GP at Swansea so Graham remains the nth longest serving manager in English (and Welsh) professional football.
But never the less he has now departed, probably preparing himself to take over from Patrick Vieira in October.
