Supposing Micky wasn't able to get a job at a higher level than L2 but Wrexham were paying the same or a bit more than Rovers. Their American owners don't know much about football, so most if not all of the footballing decisions would be left down to him. Given the suggestions of an uneasy relationship with Mark Palios, it is not beyond possibility that he would take it on.
Clough and Coleman are in post and the former at a well-financed club near his geographical base, so can't see him going.
If Micky's ambition is to manage in the Championship or higher, it is difficult to see how dropping back down to the National League, a division it can take even a good manager several seasons to escape from, would help his progress. It would seem more of a backwards step than taking the Tranmere job.
It is worth remembering that the new Wrexham owners have invested £2 million in the club, much of which is apparently going to be spent on ground improvements, as compared to the £3 million which has already been provided by the Indonesians at Rovers.
The relationship with the owners can work both ways. Yes, he would have greater autonomy at Wrexham, but would he want to work with owners that are inexperienced and potentially clueless ? There was a creative tension in his relationship with Palios.
