The toughest right-back in the Premier League has to be Branislav Ivanovic.
The beastly Serbian is a nightmare for opponents. His strength, composure on the ball and attacking prowess, have made him a huge asset to the west London club.
Ivanovic won Chelsea the Europa League when he scored a last minute header to sink Benfica in Amsterdam last season.
Kyle Walker and Bacary Sagna are two right-back's who would replace Ivanovic but the Chelsea man has proved himself versatile and looks as strong as ever, already getting on the score sheet and playing in all four of Chelsea's matches so far.
