As Ryan Giggs, Roberto Carlos, David Beckham, Ronaldo Fenomeno and Thierry Henry wind down their careers, the question on many minds is who is the next young superstar?
While players like Bojan Krkić, Alexandre Pato, Mesut Özil and Thomas Müller are quickly becoming world-class players, teams are on a mission to find the next star that will lead them to silverware.
Have you heard of Philippe Coutinho, Rogelio Mori or Romelu Lukaku? These three, along with 17 others under the age of 20, should be watched very closely.
You may see some of these youngsters already coming off the bench for their club/country. Others may still be taking baby steps and playing the majority of their minutes in domestic cup matches or hitting the training grounds with the first team.
A couple of these teenagers are already well on their way to becoming household names.
Unfortunately, a few of these players will probably end up as disappointments, but expect big things from the rest of the list.
