let me first state that i may be wrong too,coz i've only seen it in 2D, since 3D doesnt work for me anymore. so, if any one can confirm this in 3D, please do so and let me know what u see - in the 68th min or so in today's U21 INDIA VS U21 VENEZUELA match, the ball seemed to have hit the top bar after a strike from the Venezuelan striker, and yet it was ruled as a goal.
now, i'm not naive enough to believe that the 'video play' dictates the game, but i'd prefer to be naive enough to think that maybe that wrongly judged goal had a huge impact on my team's morale, and they couldn't really get back into the same after that :P LOL.
