fair point. Without sounding disrespectful, he's head and shoulders above most in the MLS, so couldn't that make him look better than he is, big fish small pond kinda thing? He has proven himself here, not as a world beater in the EPL, but he is a solid player who's experience could help the youth develop too.
I haven't followed him much outside of his stints here and then the international competitions, so will bow to your better judgement here. If he's free, and wages aren't too expensive, then ok.
