what is being muted is moving the pitch sideways, removing the main stand first, this way we will only lose 4000 seats as temporary extensions to the Kop and Anfield road would compensate. Problem is time, a new stadium from scratch takes 18mths, renovating takes 2yrs+ and is never quite the same with reduced attendances and a scruffy appearance throughout the process.
interestingly, a succesful world cup bid will have an influence on this.
