There's a good read in the NYT online in relation to New York City FC (i.e. Man City II) now five year effort to secure a site and a good fit finance structure to build it. Parallels to ourselves. Currently back to the first preferred site (Bronx v docks), now part of a wider commercial and residential development (check) and with a degree of public finance support (check). $400m for a 26,000 seater is the figure quoted. Also stressing the need for year round event business to make the strategy work (city centre location for BMD). Worth a browse.
Below link is to an abbreviated version of the article on the MLS site, NYT doesn't allow one copy and paste.. check out NYT article within the link embedded to this article.
