A player for Columbine High School couldn’t go through the opposing goalkeeper, so he did an incredible front flip over him to then score a goal. Unfortunately, the referee disallowed it, presumably because it was simply too awesome and would make even Lionel Messi feel inferior.
If I had to guess, he was probably offside. Based on his distance from the 2nd to last defender when he comes into frame.
Whatever Yanni says, goes.
