I have no idea what the second Levante defender was trying to do in the video below. He gets sort of nutmegged by Messi and then falls down.
But what always stands out with Messi when he's dribbling is how he's never afraid of losing the ball or appears to panic. Rather, he just keeps the ball close to him, shields it, and spins away from pressure or out of the clutches of defenders with a sudden burst of speed when he sees open space.
I think it's a good lesson for young players, keep the ball close and don't panic when defenders close in on you. In some ways, Messi almost invites the defenders in, saying, 'try to take the ball, if you do I will go by you.'
