Greenscene is quickly becoming essential reading for those looking to keep up with the in's and out's of the Irish football diaspora.
Particularly interesting is their Trapattoni Index which attempts to rank our senior international players in terms of their club performances. It's worth noting that, of Trap's 26-man squad for the upcoming Russia and SLovakia matches, only John O'Shea and Darren O'Dea would find their name on the current Trap Index top Irish XI (which would cull the top four defenders and midfielders, plus the two top-ranked strikers and the best goalie).
It's an inexact science (how would Richard Dunne's ranking change if he played in the Championship?) but it's a handy online guide for charting the progress of Irish players abroad.
