Whole situation is farcical. Coventry knew that Commonwealth games Rugby Sevens games were being played, but were assured by Wasps that the pitch would be ok for the start of the season (not sure they had a legal guarantee, but they have a tenancy agreement), so expect repercussions here. As someone else said Wasps are losing money, they give away a lot of free tickets (have been on some myself). They have also had several concerts there this summer, which can't have helped the pitch either but will have made some money!
The whole stadium issue is a political hot potato, as Coventry owners have been trying to get it on the cheap from the council for years, since previous owners sold their share back to the council. Indeed it's probably the only reason the investors got involved in the club in the first place. Council, understandably, accepted Wasps offer for the stadium, as it was much better than anything the football club have ever offered. Since then Coventry have ground shared with both Northampton and Birmingham due to strained relationships with Wasps and council. A real mess and another reason to be thankful that we have a decent owner!
