4. Leon Goretzka
Age: 17 Club: VfL Bochum Position: CM Current Ability: 59 Potential: 84 Just 17 years old, and with impressive potential rating of 84, the tall German midfielder is one of the biggest growth players in the game, starting with relatively poor rating of 59. He will come cheap, thanks to his age and his starting rating, but he's one to stick with considering his growth rate and overall potential, and a starting stamina rating of 75 is nothing to be sniffed at. Definitely one to buy at a low price, develop towards his potential and possibly sell on for a relatively big return. Though given how strong and solid he can become as a centre midfielder, he may be worth keeping around for lower level Premier League and European teams. http://youtu.be/4Td1EF03O6w
