Boston city fc new york athletic club
I think you may be referring to two different teams!
Boston City FC is a professional soccer team based in Boston, Massachusetts. They currently play in the National Premier Soccer League (NPSL), which is the fourth tier of the American soccer pyramid. The team was founded in 2013 and has won several regional and national championships.
New York Athletic Club (NYAC) is a sports club based in New York City, with a rich history dating back to 1861. While they have teams in various sports, including soccer, they are not a professional soccer team in the same league as Boston City FC.
If you're interested in learning more about either team, I'd be happy to help!
