As Building.co.uk reports, work on Roman Abramovich's £20m secret nightclub underneath Chelsea's Stamford Bridge football stadium may be delayed after cleaners inadvertently drenched the venue's high-tech stage and sound system. Nightclub's £500,000 speaker system and hydraulic stage were flooded by water that leaked into the venue from the stadium during weekend cleaning of the football club's east stand. Work on the club, which includes a 4m high waterfall as well as the hydraulically operated stage, was scheduled to be completed in late November but sources said the finish date is now likely to slip into late December.

Stadium cleaners used jet-powered hoses to wash down the seating area in the east stand directly above the club's stage and toilet area. To prevent any future water ingress, stadium authorities going to use a mop and bucket when they're cleaning the stand, rather than jet-powered hoses."
