Still falling. Down to about £80 now (these are the same seats the club are selling at £120). I wonder how low they'll go...

It's a relatively unattractive game with below-average demand from City fans. I wouldn't be completely surprised if resale price of CW seats on Stubhub falls closer to the game itself as people look to take something rather than nothing.
