Will Real Madrid sign a defender?

well first, if you remember when Perez came into the idea of having a galactico. He signed mostly offensive players and actually forgot to do the same thing for the defense. In that case, madrid werent fully able to be the strong force theyre suppose to be since there is an imbalance between the offensive and defensive sides. I think Perez learnt his lesson and wouldnt make the same mistake again.!!!!
