Ruben Neves only celebrated him 18th birthday in March 2015, but he's already being tipped for glory and there were even reports linking him to a staggering £29 million move to Liverpool back in January. His style has drawn comparisons to that of Sergio Busquets, with a dash of aggression and magician-like control over the ball. He's a central midfielder with 24 appearances to his name last season, including Champions League games, proving that he's got some serious experience for someone his age. He could be a very costly signing, but it's not as if he is tied down to Real Madrid, Bayern Munich or Barcelona. Porto are a selling club, so hopefully they maintain that reputation in the virtual world.
