Oddly enough, when I saw it in real time from my seat in line with the edge of the penalty box, it did not look like a penalty. Bazunu came from a long way to claim it but it looked certain that he would be there first and it looked like he was effectively body-checked in the air by the arriving forward and defender. However, looking at it on the highlights I have to agree it seems a nailed-on penalty. Seeing something in a longer context and with the wider angle you get watching live sometimes gives a very different impression.
