Juventus continue to monitor the Portuguese league, particularly Porto. Juve like Hector Herrera a lot and with Marchisio's return into form, Herrera makes a lot of sense for the bianconeri club. With Marchisio close to 100%, it seems like Juve will be looking for an alternative to Khedira and Hector Herrera is a name to watch. Napoli and Liverpool had interest in the Mexican midfielder this past summer but in the end, he remained at Porto.
