I'm not so sure it does, not for me anyhow.
Not for all, but Im sure that there are those who are overly favourable of him because he is American, and those that almost seem to hold it against him.
I couldnt care less where he comes from, as long as he performs. IMO this season he has shown flashes of brilliance and made several key contributions, but on the whole has been very 'meh!'. I dont think he has been great by any stretch and if Im honest Im a little disappointed considering the level he played at last year.
In context of the "up front" debate IMO Ade offers a hell of a lot more to general play than Dempsey and of the two I would pick him. Dempsey doesnt add a great deal when not scoring this season.
I do hope next year, having settled in, we see more of the Dempsey Fulham did.
