Nice goal by Di Canio. Though they're completely different. Del Piero's goal is much more difficult to score from football wise of view.
The way he positioned himself, taking the shot with his left foot without bending his body is a lot difficult than the goal you posted. Di Canio's goal came from cross also, Del Piero's ball went like what 7 or 8 meters up the pitch? Del Piero definitely.
