Given the shortage of options we have of who would want to manage us at the moment, I wouldn't be against taking a risk on one of these guys, but it's extremely unlikely.
If the Yanks refinance the only possible change of manager we could get is Dalglish, and even then it seems extremely unlikely to happen. If we get sold then the new owners are going to look to someone more high profile. Not just because hopefully we'll be a more attractive club to both players and managers alike, but because the owners will want to stamp their mark on the club, and I doubt this mark will include searching through the lower divisions for the next up and comer. New owners like big statements, and the manager of Doncaster hardly fits this bill.
I do agree with Brendan and Ross that we need someone young, ambitious; someone who will build a new era; someone who will gut this squad, start afresh and get them playing winning football.
Thankfully it's not my job to find that person.
