After moving to Manchester United in the summer of 2003, the then-18-year-old future Ballon d'Or winner made his international debut in August the same year. Positioned on the substitutes' bench alongside Jorge Andrada and Simao, Ronaldo would make his full Portugal bow in a friendly against the mighty Kazakhstan. At present, CR7 has well over 100 caps for his country, is their all-time top scorer, and was recently voted Portugal's best ever player ahead of the likes of Figo and Eusebio. With a skinny frame, gel-heavy hair, and an almost nervous glance, this was a Cristiano who had a fair way to go to become the world-beater that he is today.
