#7 Radja Nainggolan
During Nainggolan's four year stint with Roma, he established himself as one of the best creative midfielders on the planet. He made a total of 204 appearances for Roma and was a part of the Serie A Team of the Season three years in a row.
Nainggolan completed a £34.20m switch to Inter at the beginning of the window, with Davide Santon and Nicolo Zaniolo heading the other way. The addition of Nainggolan means Inter have one of the best midfields in the league, with Matias Vecino, Marcelo Brozovic and Roberto Gagliardini all a part of the side as well.
Inter finished 23 points off table-toppers Juventus last season and will hope that the Belgian's presence can spark them to a title challenge this time around.
