Nathan is right of course. The problem higher up isn't that there are loads of foreigners in the Premier League, the problem is that English players just aren't good enough so clubs have to bring people in from abroad. Italy and Spain have similairly rich, globalised leagues and they run on mainly native talent.
The problem goes way deeper than Arsene Wenger, it's a problem with our footballing culture itself I'd say. An overemphasis on physical size rather than skill, a win at all costs mentality in games for ten year olds, the general dislike of the idea of sport for sports sake.
I could go on.
