U20 Quarterfinals Referee Appointments

FIFA has chosen the next four referees who will be in charge of the quarterfinals of U20 World Cup 2011 held in Colombia. Although I had them in "Nuestras Designaciones" (in Carlos' blog) as well, they are a bit problematic as FIFA did not seem to have thought of the last four matches...I am excited how they will manage that.
These are the appointments:
