The last I recall off the top of my head, is Haydn Mullns temporarily being interim manager of Watford. I think he also had some involvement with West Ham as a coach after, but his wiki doesn't clarify that. He was indeed head coach of Colchester United under Steve Ball. Who knew? I didn't.

Also, he seems to have managed "Turks and Caicos Islands", I don't recall hearing of them before.

 

i liked hayden mullins when he played for notts, i though his experience helped and when we pushed him into the centre back position i though he did well enough. it was a shame we did not have a bit more quality that season but he seemed a good player.
