Poll: Who is the best Barcelona defender at the start of the season?

Perhaps the best thing about Barcelona's start to the 2014/15 season is the team's defense. Under Luis Enrique, the Blaugrana have conceded only three goals, keeping a clean sheet in eight of the nine official games of the new campaign. Only Paris Saint-Germain got to score on Barça thus far.

Enrique's job to improve the defense is certainly something worth noting, but the players have also done a marvelous job. New signings Claudio Bravo, Marc-André Ter Stegen and Jérémy Mathieu have had mostly good performances. The old guys -- Gerard Piqué, Javier Mascherano and Marc Bartra -- have also played and given their contribution on Barça's spectacular defensive start.

We want to know your opinion: who's the greatest responsible for Barcelona's great defensive performances so far? Talk it away!
