I see it only as the East Coast because so many US blues are on the East Coast, including New York. Once the Portland Timbers become a MLS team next year then Man City will produce a link between the 2 clubs and start annual matches on the west coast.
That said... it is nice to have an official annoucement. Ever since Renya signed with the blues I have followed no matter what, and now they are going to repay my commitment. I like it. So excited as an American Blue right now
