We all can identify the stars of today's game without much trouble. From Messi to Malouda, the names come to our heads in an instant when thinking about the beautiful sport. After years of watching them, we have memorized their styles, attitude, work ethic and basically every other known attribute that the player contains. However, soon these characteristics that are branded into our brains will have no direct use when watching a casual game of football.
Roughly every five years, the stars of modern football cycle out and a new generation comes in.

This being said, fans always have to stay updated on who's rising the ranks of football to increase their overall soccer knowledge. Let's admit; you don't want to be the last guy who finds out about the next Ronaldo or Messi. That's just embarrassing.
