Kerlon. Ball Genius, or weak opponents? Both?

In the video (2 minutes) the player highlighted by a fan is Kerlon. He has good skills, no question.
Here is my view.
#1. Five or six of the clips cut right as Kerlon loses the ball to the other team.
#2. As in the first few clips, the way to defend this is to just agressively (staying goal-side) go after the ball. Remember, if the ball is in the air, it is free to play.
#3. The second minute shows a lot of defensive weaknesses: Goalkeepers coming out when they shouldn't, and defenders lunging at the ball instead of being in position.
Still, Kerlon's good.
