The clue may lie in his resignation statement - says the full on 24/7 management "especially in the Premier League" isn't for him any more, wants to enjoy life while he is still reasonably young and healthy. But somehow you can't imagine him sitting around at home pruning the rose bushes.
So instead of the hamster wheel of steering clubs away from the drop zone, he could work for us in a more relaxed way; partly as an investor, partly as a different and less intense role but keeping his hand in within football, partly as a retirement project. It would give him the chance to work in a business he co-owns, and he'd be able to work on club development in a less "coal face", more strategic way - maybe not full time but certainly in a overseeing role where he could influence our longer term development which you can't do as a manager.
