What Ronaldo's shot do differently is not slow down as quickly as other peoples shots. You've got to admit it is rather unique and I don't remember seeing somene recently manage to shoot the way he does from long range. Hi technique, which may just be luck of his style, manages to get next to zero spin on the ball which is what causes the ball to slow quicker normally. I'd imagine that makes life difficult for a keeper as the ball is travelling differently.
Having said all that, last nights was very saveable.
It's called a toe punt, I invented it in the 80s.
