Bianconeri eye Marquez as Bonucci back-up...
The Bluagrana's directorate have informed Marquez and his entourage that he is no longer a part of the club's plans for the season ahead as coach Pep Guardiola prepares to sign a new deal.
The player's agent Enrico Nieto is now tasked with finding him a new club, and Juventus seem first in line to offer him a solution.
Giuseppe Marotta is said to be testing the waters in Barcelona, knowing there is also an interest from Genoa and Galatasaray.
Marquez used the World Cup as a shop window for his services with some good displays, and he is seen as an alternative to Leonardo Bonucci in central defence.
Meanwhile, Juve's pursuit of Roma's Philippe Mexes continues, but the move is on hold because of the capital club's Unicredit takeover negotiations.
