Porto has long been known as a team that nurtures talent in Portugal before selling them for a massive profit.
This current squad is no exception. Youngsters including Juan Iturbe, Juan Quintero, Hector Herrera, Alex Sandro, Danilo and Eliaquim Mangala are set to play important roles in the side.
Juan Iturbe, the attacker on this list, has yet to live up to his billing as the next Lionel Messi.
With that being said, the 20-year-old is in the right place to fulfill his potential.
Juan Quintero and Hector Herrera are new additions, and both have seen their stock rise massively in the last year or so.
Quintero, one of Colombia's bright talents, drew attention with some fantastic displays with Pescara during the 2012/13 season. He continued his good form at the recent FIFA U-20 World Cup.
Meanwhile, Herrera's rise came mainly through his performances with Mexico during the 2012 Olympics. He is now set to bring his all-action style of play to Europe.
Alex Sandro and Danilo are two Brazilian full-backs, though Danilo is capable of playing elsewhere. We'll get to them a little later on in this slideshow.
Eliaquim Mangala made his debut for the French national team earlier this year after impressing during the season with Porto. Tall, strong, good in the air and with decent pace, the 22-year-old Mangala may play a part in France's resurgence on the international stage.
