10. Kostas Manolas and Yanga Mbiwa
The AS Roma defending duo have grown through leaps and bounds in the recent times and have forged a partnership that is nigh unbreakable. The fact that Roma have conceded only 7 goals in the league this season serves as a testament to the tenacity and guile they have brought to an otherwise porous set-up. Roma narrowly missed out on the league title last campaign and to contend a challenge this time, the defensive double need to be at their best.
