Think a good starting point would be firing out some questions to each group. Make them as unambiguous as possible so they can't wriggle out of answering.
Off the top of my head something like this:
CCFC
Have you requested an extension to the current deal?
If yes have you requested the extension on the same terms as the current deal?
What is the longest term you would be prepared to sign for, assuming the same terms as the current deal?
CSF
Are there any plans, either formal or informal, for the facilities required for the current standard of academy to be removed and / or replaced?
Has a longer term deal, on the same terms as the current deal, been offered to CCFC?
What is the minimum term you would require for the academy facilities to remain in place?
Are there any plans, either formal or informal, for Wasps to use the Higgs Centre and / or adjoining land as their training base?
CCC
Have any discussions, either formal or informal, taken place regarding facilities at Higgs Centre with any other group?
If yes has anything been discussed which would prevent CCFC continuing to base their academy there?
If yes has anything been discussed relating to Wasps using the Higgs Centre and / or adjoining land as their training base?
WASPS
Have any discussions, either formal or informal, taken place relating to Wasps using the Higgs Centre and / or adjoining land as their training base?
If yes has anything been discussed which would prevent CCFC continuing to base their academy there?
