I'm assuming the poll is regarding who we consider the biggest club??? If so I 'd have to say Manchester United, taking into account recent history and past history, domestic and European success.
Chelsea has no historical success or European success to speak of.
Arsenal has no European success and less domestic success.
Liverpool has had not much recent success domestically.
Manchester United has all the prerequisites.
Horse shit!
