Whereas many full backs on this list are primarily feared for their attacking prowess, Hector Bellerin has demonstrated equally impressive defensive ability. The young Frenchman looks set to become a first-team regular for Arsene Wenger this season, despite originally only filling in for injuries. Bellerin's pace is fearsome, but he doesn't rely on it to get him out of trouble. His defensive positioning is also usually impeccable, making him an incredibly difficult opponent to break down. His good form continued with a committed display in the Community Shield, contributing towards a clean sheet against defending Premier League champions Chelsea.
