You must be sick of this subject Duffer
, but i can tell you now - you'll never win the argument mate. Chelsea & City will never be respected by rival fans in the same way United, Pool & Arsenal etc. are. You bought success & that's the stick rival fans will beat you with & they're right too aswell.
Chelsea changed the course of what clubs will pay in transfer fee's / wages, and in doing so ruined the landscape for the worse. Their oil money was the only reason they became an attractive proposition for top players & no-one could compete, or were willing to compete with that kind of spending - us included.
Chelsea might be popular in Africa because of some of the African players you've had over the last 10 years, but those fans will always be plastic & in many cases, will shift allegiance from season to season depending on which team is shit-hot right now. Many follow the player & not the club also.
Liverpool have way more of a following worldwide than Chelsea - its laughable & naive to think differently!
