STAMFORD BRIDGE = LIBRARY

Chelsea fans are so silent that you can actually hear the noise of a pin drop.
I mean Chelsea are playing against their number one rivals at home and have a point to prove. So would at least expect their fans to get behind their backs. But no. Fulham fans are actually out-singing their West London counterparts.
I mean the Emirates was previously known as the library but Stamford bridge is making it look as electric like Old Trafford or Brittania.
What is the reason for this? Have the Chelsea fans jumped ship due to the rise of Man City as they jumped ship from Fulham with the rise of Chelsea 8 years ago? Or do they sense the eventual sacking of AVB?
