Can't imagine MM doing that. There'll be some casualties and he obviously doesn't do sentiment given his marginalisation of Earnie.
I think it'll be a case of feeding 3-4 players of extra quality into the team, a couple team members become squad players with a few disappearing out the door. Saying that, there are very few players who have a place nailed. Marhsall, Hudson, Whitts and Beallmy are written in stone, with Taylor and Turner there as there aren't any options but would probably stay.
With Campbell and a returning Maynard we probably need to replace HH and Rudy. The midfield is near enough OK but I wouldn't say no to another bit of quality alongside whitts. 2 more fullbacks would be necessary.
