It won't happen until the situation with Thohir is concluded.
If he comes onboard, the club can save face by replacing all and sundry with a new team that was "part of the deal" and although they were "fully supportive of KR and his team", the change would be in the "best interests long term blah blah blah". No admissions of guilt, no blame being apportioned, no honour lost.
As an aside, KR came to a club last year and turned an underperforming, uncommitted bunch of no-hopers into a semblance of a team and saved us from the drop. In the summer, he appointed Shaun Derry. Draw your own conclusions.........
