Today they are some of the best players in the world, all well styled by teams containing dozens of PR experts. But how did they scrub up when they first started out?
In this gallery of images you can take a look back at how some of the greatest footballers in the world looked on their debuts, and compare them to how they appear today.

Note: For some of these footballers, we were unable to obtain licenses to show images from their actual debuts. In these instances we have shown images from games played no more than a couple of months after their debuts instead - they still look the same!
