Well, bad sportsmanship or not, no one can really blame Nani. Strictly speaking, he played by the rules, and he did play by the whistle.
If the referee had blown his whistle for a free-kick to Spurs, or a penalty to Man U, this would have been a non-issue. The ref made the mistake of not making his intentions clear, and Gomes made the mistake of thinking it was a free-kick.
the bottomline, mu was leading by a legitimate goal, and despite what harry has to say, it is the score board that counts, not "what ifs"..
It's Gomez's fault, he didn't play by the whistle.
Its a small issue if u compare this incident to the infamous "hand of god" by a "certain argentine."
