I understand where you are coming from, but I think the reflected glory of a CFG owned entity is much more vibrant and acknowledged on your side of the pond. The City US fanbase is considerably more vested in Manchester City than NYCFC. Should we continue on to win trophies in England and potentially Europe, there will be much more joy over the success of MCFC than that of NYCFC winning the MLS Cup.
City supporters over here are much more concerned about the parent club than any of its children.
Just my opinion as a Yank, but I think that a Portland Timbers fan can't be bothered or concerned with CFG investment in the MLS.
