Having been to a fair few Chelsea games as a neutral, yes the west stand tends to have more of the tourist / neutral supporters. Interestingly the re-sale website I believe most Argyle fans including me seemed to have used has more availability in that stand.I get the impression the West Stand usually contains lots of neutrals anyway. The very large clubs always get loads of neutrals in attendance, particularly given Chelsea's location.
I do know of individuals who buy a season ticket at Chelsea as an investment and then sell on nearly all the home games as demand is always there and make enough money to fund their own season tickets so it’s a win win …..
livefootballtickets is still showing availability for home tickets from £63.00 + fees for the FA cup game.
sadly it seems it’s all about supply and demand….
