You say it's your opinion[which it obviously is] but you are very dismissive and contemptuous of any alternative[including my opinion].
The wholesale changes bit is very up in the air no matter who the manager may be because nobody knows how many of the current squad will still be here.
Wholesale as in : Management Team, Playing Staff , Tactics , Targets etc And all within an 8 week window???
You'd have to employ Clark Kent to manage that lot successfully.
I am not being dismissive, just being realistic in terms of what is and isn't achievable to be fair?
A new manager brings with him uncertainty, some of the current out of contract players might see this as the straw that broke the camels back and leave as a result.
At least with Ronnie they know what they are getting.
Like I said, you are more than welcome to your opinion, I just think we would be better ploughing our efforts and energy into improving on what we've already got in place.
