Anyone looked at Graham PotterI really like what he has done at Ístersunds. Here is a cool article about him.
For his Mangerial career I hope he avoids the UK and stays in Europe for a while though. He wouldn't get the time of day in England (from the he has never done it at a proper team brigade). He needs pedigree elsewhere first sadly as I think he would be a good management choice for a Championship side at the moment.
I could see him moving to Bundesliga 2 or maybe the Dutch league next, and being a success.
