The bald headed guy at near post was half a yard offside
The whistle blew before the guy scored, the Slovenian's stopped playing
I didnt see the game, just a replay of that disallowed goal... I didnt see any significant holding or obstruction, but US player was offside so the right decision that goal wasnt allowed even if the foul was given for the wrong reason.
Video is on BBC and it freezes as the ball is struck, go and have a look, very very clear offside.
Slovenia 2-2 USA
