#1 Jerome Boateng
When someone like Pep Guardiola calls you the 'best defender in the world', it should speak the truth more than most other opinions. The German has been a rock at the back of Bayern Munich. With him in the side, they've rarely lost a game or conceded any goals.
The 27-year-old is now heading into the peak of his career with the club and if Barcelona do sign him up, will inherit all his best years. He's quick, extremely mobile and while Lionel Messi showed him the door last season in the UEFA Champions League, remains one of the best defenders in the world.
His aerial ability could equally rival Pique's and he's hunger for defending right could be a huge boost for Barcelona. The Catalans, however, will have to pay quite a bit of money for the German considering his new contract but when they did the same for Luis Suarez, they can for Boateng. He's equally as worthy.
