FFS. It's a mild dig at those in red & blue who love to tell us how passionately well supported they are at all times, and who like to refer to Albion fans as plastics and JCLs.
The point being that all clubs have their share of fairweather fans...
How dare you even suggest that Selhurst isn't full. It's as full for Villa as it would be for Chelsea or Arsenal at home. There are no plastic fans or JCLs at Palace. No sir.
