The Daily Mail, meanwhile, name that figure more exactly at £800,000, or over £1M including Docherty, and claim that the Dons are demanding that money is paid before Rangers can even open talks with McInnes.
What is clear is that Milne is determined not to lose his boss to his club's main rivals for second place.
Rangers have been without a manager since Pedro Caixinha was sacked in late October.
But with no shortage of interest in McLean from south of the border, Rangers will be hoping that they can finally lure McInnes to take one giant stride towards completing an exciting double deal that should improve their prospects both on the pitch and in the dugout.
It is understood that McInnes will meet with Dons chairman Stewart Milne later on Wednesday to discuss his future.
Five months on, Rangers will have to guarantee him adequate time and resources to challenge Celtic if he's to agree to draw a line under his four-year tenure in the North East.
Compensation would have to be agreed between the sides if McInnes was to return to the club he served as a player between 1995 and 2000. It hasn't been as straightforward as it should have been over the last few weeks'.
'It is a ridiculous amount of speculation the Dons manager has had to work under and his players have had to cope with, ' he said.
"Rangers can not allow the situation to drag on longer as it then makes the Ibrox board look like they don't know what they are doing", Miller added.
It remains to be seen whether Rangers will back off having had permission to speak to McInnes refused, but the Aberdeen boss appears to be the Ibrox club's preferred candidate for their manager's post.
