Depends on the football you're aiming to play. I sure think a side aiming to have 60% possession at all times should have an excellent passer at the back.
See what Dante said about in recently in an interview:
"Every big team in Europe now focuses on possession and moving the ball around and Brazilian defenders are very suitable for this kind of game because our school of football values the pass," Bayern's Dante said. "We are also much more comfortable going forward, another requirement of the style of game that is being played now by teams like Bayern and Barcelona, for example."
