That is just a fantastic strike. The service from Faouzi Ghoulam is also excellent, but my god that finish is so perfect and instinctual, and struck so much harder than it looks at first blush. Look at Bizzarri's hands: he actually gets them up to try to block the shot, but the shot just blasts through them.
Really, if you can make the other team's fans chant your name after scoring a goal, you know you did damn well. That goal was just brilliant.
