To my surprise and delight, Zonal Marking, one of my favorite soccer sites out there, did a trademark analysis of this match: http://www.zonalmarking.net/2011/01/21/japan-3-2-qatar-kagawa-helps-japan-into-semis/
Nice, thx for the post! On a different note, for those who are still questioning Qatar's first goal (sorry wanted to post this earlier but don't have the necessary tools to do this at my home PC). Clearly shows Sebastien is indeed onside.
