Irish Managerial Highs And Lows

was a little bored earlier, so I went through the history of Ireland games on soccerscene.ie to see who are the highest ranked teams defeated, and lowest ranked sides lost to by Irish managers in competitive games, by matching up the teams with the rankings on fifa.com
here are the results:
