We've been played three times over property deals and always emerged in a worse state than when we went into them.
This time it's with, possibly, I'm not sure where the money comes from, a local authority. Sadly those guys are hardly models of financial probity.
If a hotel, conference centre, essential to the deal as a stadium used a few times a year won't fill the coffers, was such a good idea then why isn't there one there already?
What basis is there for suggesting that a stadium could be filled for home games? With interest rates unlikely to return to near-zero levels the interest charge alone will be huge. Lenders will think "Wasps? Oh yes, Coventry. What a mess. No thanks." and pass on the deal.
We haven't been living in the real world for some time now. Stadia, hotels, players, all cost money. Cut your cloth according to your means.
