Napoli want Mascherano

Napoli is working out a deal to try to get Barcelona FC's Javier Mascherano to join the club as the current Napoli Rafa Benitez has worked with the player before at Liverpool and know the player quite well and would want him to join his team. However Mascherano is currently Barcelona starting central defensive option and they would unlikely want to let him go without securing the services of a full time central defender first.
